9/21/2025 contacted with [phone service aompany] and [apple] about which issues "mi16556" error made me cant call out. Here is conversations:
phone service :
me : my apple showed "mi16556" error
can you please verify the account through ICCID and IMEI? The ICCID is a 19-digit code located at the back of your Ultra SIM, starting with 890. Kindly dial *#06# on your dial pad to get the IMEI.

me : [cell phone click Settings , General, About, got ] typed IMEI and ICCID
Thank you. It appears that the service does not support your device. I would suggest to use a newer model instead.

me : may i ask you "mi16556" error issued by your service ?
That is actually not prompted on our end; that is your operating system on your current device, as the Apple iPhone 6 is really not up to date anymore.

me : did you mean apple can terminate your service (i mean disallow me call )?
For more clarified answer, you can contact apple customer support for your device compatibility checking on their end as well

me : does it mean if i pay att phone service(in stead yours) then can solve the problem?
As mentioned earlier, the defect is on the device not the service
me : i see. can i get refund that you knew my device cant get your service ?
Unfortunately, no refund is allowed at this point as the service was already exhausted and activated.
Is there anything else that I can help you with?

me : may i ask you how to find out your service for available cell phone listing ?
You can use this link https://phones.ultramobile.com/ for our available compatible devices
me : we bought from bestbuy and have no idea how many years can continue use your service. does your company showing how many years ?
Yes, you can still use our service as long as you are renewing your plan

me : i did but your plan didnt give me the warring.
Here is the current start and end date of your plan 02/21/2025 - 02/21/2026
Ultra Mobile
Once you have purchased a newer model device, you can download the application as well to keep track on your usage.
me : but my cell phone already cant call after renewed
me : do you know my concern? i have no problem to renew. the problem is your company didnt tell me i would suffer the problem. i have been tried to solve the problem by Google searched but no way to solve the problem until yesterady showing need to contact you.

It seems like you are trying to activate wi-fi calling on your account, however your device does not support wi-fi calling anymore as the iphone 6 is the least iphone existing on the market and upgrading your plan is the best way to resolve it
me : the wifi calling is by google searched yesterday before didnt set wifi calling on.
i dont need wifi calling but old time(ps traditional) call which is not work either.

The main point here is the reason why you cannot use your device and the service to its potential it is because it is really outdated at all, you can also check that at google
No, the iPhone 6 is not officially supported by Apple and does not receive the latest iOS operating system updates. Its highest supported version is iOS 12, and it stopped receiving security updates around 2021. This means its vulnerable to security risks and many modern apps will not function correctly. The iPhone 6s major software (iOS) support ended when it stopped receiving iOS updates, with the highest version it can run being iOS 12. The iPhone 6 was declared an obsolete product in 2025, meaning it is no longer supported with hardware repairs or software updates and may have security vulnerabilities. While the device will still function for basic tasks like calls and texts, its age and lack of updates make it impractical for most users.
me : i tried all google searched it didnt say apple 6 plus cant call (spouse apple 6 ES still working)

but it will be significantly limited due to its inability to run any iOS version beyond iOS 12. You can expect poor app compatibility with newer applications, slow performance, limited storage, and outdated security, making it unsuitable as a primary smartphone for most users in 2025.
me : as you mentioned it could call but mine cant this is why i chat with you to find out how to solve the problem
i can disable wifi on now, would you please stay with me and i can try call out see whether you can find out the problem in your side?

It appears that there is no usage on this account for calls and texts.
Your account is properly provisioned here, and it appears that there is no single usage on the current monthly cycle.
me : what did you mean? i havent disable.
just disabled, so now i am going to call, can you verify in your side?
now it can (call). but let me try 2 more times.

There is no way for me to check you call history or ongoing calls
me : now the same "mi16556" error showed up wont allow me to dial 2nd time.
can you inquire your company ?

If your device is fully supported by apple, there would be no service issue on your end.
Hey there! Just wanted to check in and see if were still connected!
me : so it has nothing to do with your company that your system didnt block my call out but apple itself auto block after i called 1st time succeeded?
it sounds like "your prescribed?.. is not in service, if you feel received wrong message please redial later, message "mi16556" error
sorry my english is not great... i did google searched, yesterday showed i need contract your company.
it showed as: ...Contact Your Carrier: If other steps fail, the issue may be on your carriers side, so contacting their support is a crucial next step.

Do you have a screenshot for that specific error message?
me : as i said it didnt show but after i dialed got voice

As a customer support I am advising you to upgrade your device or contact the apple customer support.
If you insist, even troubleshooting steps wont help on unsupported devices.

me : do you have apple customer support phone number ?
Here is their phone number 1 (800) 275-2273
me : thanks. i would verify with them whether their iOS issued the "mi16556" error to forbid user call out. thanks

i called apple support, lucky me got some one picked up, and he did help me so he can see my cell phone screen by Settings Cellular ON, then popped up screen to authorized him ...
ps certainy router admin need to connect cell phone and windows settings too.

the problem is when i tried to make call the screen showed FAILED in stead auto voice "mi16556" error, so the man told me he cant do aynthing about it in his side. i was told the only way is to try reset cell phone network, power off then on, toggle airplane mode on and off... as those posters suggestion that only allow one time call out.

after he hanged off i tried again it became auto voice "mi16556" error (in stead sreen shows FAILed) again.
......................................
spouse just paied his yearly phone service on July, so searched [when would apple 6 ES stop updating ?] got [Can I still use my iPhone 6s Plus in 2025?]

AI Overview No, the iPhone 6s Plus is not good for use in 2025 as a primary device due to its lack of software updates, which means no new features, security patches, or app compatibility. While the phone still works for basic functions like calling and texting, it will have slow performance, degraded battery issues, and significant security risks. For a worthwhile smartphone experience, consider newer models like the iPhone 11, SE, or 13 and above. ....
What you can do with an iPhone 6s Plus in 2025: Basic Tasks: It can still perform essential functions such as making and receiving calls, sending text messages, and light web browsing. -----> You see the real problem who issued mi16556 ?

Backup Device: It can serve as a simple backup phone for calls and texts.
Creative Tool: The single camera and older software can be used for creative photography and editing, though its limited

What to consider instead: iPhone SE: The iPhone SE (2nd or 3rd generation) offers better performance and compatibility with the latest iOS versions at an affordable price. For a much better experience, consider a newer model like the iPhone 11, which is a great affordable alternative, or even the iPhone 13 and above

--searched {Does Apple sure that [mi16556] wont maliciously enforce on Apple 6 ES ?} got : Searching for information on the error code "[mi16556]" reveals that it is not a known, official Apple system error code. Instead, it is likely a fabricated code used in phishing scams. Apples standard system error codes are numeric and typically shorter, such as error 11 or 53.
Here is what you need to know about the [mi16556] error and malicious enforcement on an Apple device:
The code is a scam. The error code "[mi16556]" has been seen in fake "Apple Security Alert" text messages and pop-ups designed to trick users into believing their device is at risk.
-- to allure users buy what ? i dont buy it, it saying if you feel it is wrong message, please dial again. not tell/allure you to dial fraud phone number.

Malicious enforcement is unlikely. Apples modern security systems, including memory integrity enforcement (MIE) on newer iPhones, are designed to make it extremely difficult for malicious software to gain access to the operating systems core functions. Your iPhone 6s, however, has not received major security updates since iOS 15 in 2022, which makes it more vulnerable to potential threats.

How the scam works: The scammers goal is to create panic and trick you into calling a fake "Apple Support" number. On the phone, they will attempt to steal your Apple ID, password, financial information, or install malicious software by guiding you through fake "fixes".
----got 1 (800) 275-2273 from phone service company which is not fraud phone number. and dialed from spouse cell phone.

Protecting yourself from malicious enforcement
On any Apple device:
Do not engage. Do not call any number provided in a suspicious text message, email, or pop-up. Apple will never ask you to call a number from an on-screen alert.
Contact Apple directly. If you receive a legitimate-looking alert and are concerned, find the official Apple Support number on Apples website and contact them directly.

--i did but weird thing happened which showing failed on cell phone screen and apple support man can see it on my cell phone screen. told me he cant help in his side after hanged off it back to auto voice again, isnt creepy ? i can Erace all content and settings which already did this year. in 2025 the only updated app is from apple that in Reset can see 6 options in stead original only 2 options. no way to stop apple upated. the more functions the more back doors or holes leaking.

Use the official App Store. Avoid downloading apps from unofficial app stores, as they do not have Apples protective screening for malware.
Update your software. On a supported device, keep your operating system updated. Security updates patch vulnerabilities that malicious actors could exploit.

For your iPhone 6s:
Be especially vigilant. Because the iPhone 6s no longer receives security updates, it is more susceptible to malicious attacks. Avoid clicking on links in unsolicited messages or pop-ups.
Back up your data. Regularly back up important data from your iPhone 6s to a secure location, like your computer, in case of a security incident.
Consider an upgrade. For the most robust protection, your best option is to upgrade to a newer iPhone that still receives the latest security updates and features like Memory Integrity Enforcement.

--be honest PC MS defender cant protect data files auto disappeared whenever File explorer, notepad auto switched different versions or MS updated caused deadly problems. do i believe hacker or blackmailer did? less and less that MS defender on line and off line showed 0 threats found, no others but iobit apps related left debris and cant be remove by defender off line . cell phone data files is 小意思.

if MS can tell us what is 觉醒意识AI the rules and when File explorer, notepad will auto switch versions to prove they have nothing to hide or maliciously punish certain users by very frequently auto switch different versions.

searched [who issue mi16556 error to apple 6 plus that cant allow users call out?] An error code MI16556 on an iPhone 6 Plus is issued by your mobile carrier, not Apple. This message is not a standard error but a custom one from your service provider, indicating a network-related issue that prevents you from making outgoing calls.
--it was not connect to network until got this and that cant receive phones calls or cant call out... then connected to find out problems and tried posters suggestions.

Possible causes of this error from your carrier include:
Billing problems: Your account may have a billing-related block.
---> it is not over due date (2026 Feb) yet.

Service issues: There could be a local network outage in your area.
--->not my case. spouse apple 6 ES no problem, mine after reset... can allow only one time call out.

Account misconfiguration: Your account may not be properly configured for your specific iPhone. ---> really? how come only one time allow to call? ps i think it is highly possible after 2nd time chat with phone service then problem auto disappeared.

How to troubleshoot the issue
You can try the following steps to resolve the problem. If they do not work, you must contact your carrier directly to solve the issue.
Contact your carrier: This is the most effective solution, as the error originates from them. They can check your account status, update your settings, or inform you of any network outages.
--- obviously apple and phone service company workers all denied. ps 2nd time chat with phone service to request update ultra/mint mobile 36.1 new version but the problem auto disappeared.

Reset network settings: On your iPhone, go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This will erase saved Wi-Fi passwords and network configurations, which can resolve bugs.
---it helped but only allow one time call.

Toggle Airplane Mode: Turn Airplane Mode on for a few seconds and then turn it off again. This forces your phone to reconnect to your carriers network.
---it helped but only allow one time call.

Check for a carrier settings update: Go to Settings > General > About. If a carrier settings update is available, you will see a prompt to install it.
---showed ultra/mint mobile 36.1 , no showing update available. so searched [ultra/mint mobile 36.1 has new version ?] An outdated reference from 2019 mentioned "Ultra/Mint mobile 36.1" in relation to an iOS issue . Since then, both Ultra Mobile and Mint Mobile have released numerous app and system updates. You should update your phone to the latest version of the carriers app from your phones app store.
searched [how to find ultra/mint mobile 36.1 new version in phones app store?] On an iPhone: Open the App Store. Tap the Search icon at the bottom right. Search for "Ultra Mobile" and select the app from the results. If an update is available, you will see an Update button on the apps page
----> click bottom [updates] it shows no updates, all your apps are up to date.

searched [will carrier ultra/mint mobile 36.1 caused apple 6 plus cant call out ?] Contact your carrier: Contact Mint Mobile or Ultra Mobile for support and to confirm if they have discontinued full support for the iPhone 6 Plus. They can check for account-related issues or service outages in your area. ps 2nd time chat it auto recovered.

[apple 6 plus showed carrier ultra/mint mobile 36.1 can it update to new version?]Yes, you may be able to update the carrier settings on your iPhone 6 Plus, but not the iOS version to a "new" version
--->very likely phone service company didnt or stop in 2025(2019?) ps tried 2nd time chat to request got our money without refund must update new version but it auto recovered before requested.

Remove and reinsert your SIM card: A loose or improperly seated SIM card can cause network issues. If you have an older iPhone with a physical SIM, eject the tray, check the SIM for damage, and reinsert it.
---just did not help at all. ps 2nd time the worker denied and refused to refund 2 months which in 2025 till today got all kind problems and worse to worst.

9/22/2025 tried call out 3? times not problem, then when i really need to call doctor office to confirm cancell appointment as cant get pre-estimate copay the weird auto voice showed up again. cant but use spouse iphone due to the office also cant tell so told me some one would call me back, i warned her must call spouse phone number because my iphone still not stable. several hours later a female called me again cant tell the procedure code that requested by hospital so can estimate the fee. not sure when can get answear.
the thing bothered me such MI16556 error really came from scam or phone service company? any limit times to call out? why cant tell in public ? if it is scam does that mean usa government cant catch the bastard (all the time robot auto voice) ? if it is phone service company why wont admit it ? such error code caused by too many poor seniors people as me-type made calls at same time ? ps only use it to call out or receive phobe calls and text messages. i have no willing apply wifi connect in small cell phones but i must verify whether it can connect because apple still update apple 6 plus (and 6 ES) for apple store and other apps.

9/23/2025 if it is not banks, investment company, SSA ... request must individule owns different cell phone, email account but ignore the retired seniors especially over 75-80+ years old hardly can deal all kind problems, not mention less and less income such as investment dividends, interests (cash). plus SSA yearly adjust and increase % much less than utilities, foods, taxes, oil, insurance... jump up. why would i want to prepay yearly cell phone that any time cant call out or receive phone calls, text messages ? we both worry such MI16556 error happens to spouse apple 6 ES soon.
in fact even myself this year as 68 cant deal with MS frequently updated problems and this year my cell phone frequently got problems. should usa government for seniors offer free education how to avoid these problems ?
