If your SIM card isn’t activated or provisioned, it can affect various aspects of your connectivity. A notification will appear in your settings that the card cannot be used until it’s been provisioned. “SIM not provided MM2” is a pretty common problem.
It can be caused by a number of things, but the good news is that, in most cases, you can fix it easily on your own. In this article, we will discuss the most common causes and offer you a few quick solutions.
SIM Not provisioned MM2 – What Does This Error Message Mean?
Mobile devices display various error messages. The error message “SIM Not Provisioned” means the SIM card still hasn’t been permitted to operate on your carrier’s network. You must activate any SIM card before it can work, but if you had previously enabled yours on the same phone, anything else could have caused the problem.
When a phone starts up after a shutdown, the first thing that happens is that it scans for a SIM card. Detected sim cards can usually operate as expected – you can make calls, send text messages and use cellular connectivity. If the mobile phone does not identify the SIM card, you can’t do any of these things.
This error message basically informs you that a SIM card has been installed but cannot be accessed.
Common Causes of the Error
Various reasons could cause this error message. A GSM provisioned error could be caused by a carrier issue but could also be caused by a broken SIM card or SIM slot. The “SIM Not Provisioned MM2” problem can also be caused by software or hardware bugs on your phone. This error can also occur if you have been off your carrier’s network for a long time and have lately returned to their coverage.
Finally, the least probable reason is that your smartphone is locked and can be used with SIM cards issued by only one provider. That means it will accept SIM cards from providers you have a contract with and not any other provider.
How to Activate AT&T SIM Card When Using an Unlocked Phone
New SIM Card or Sim Card Replacement
If the card is new and upgraded, it must be activated before accessing the internet or making and receiving calls. After purchasing and placing the SIM card into the slot, activation is a mandatory step to make the card accessible.
Broken Sim Card Slot
The sim card placement slot sometimes might be bigger or smaller than the size of the SIM card. In this case, the size of the SIM card and the slot will not match; hence the card could be damaged or not detected.
Poor Network Coverage
Different places have different network coverage and different service providers available. In some locations, the AT&T network may not be available, which means that your connection will also be unavailable. The connection problem is common near airport areas.
How to Fix the Error Message

It is essential to ensure that the SIM card is correctly inserted. Remove it, and reinsert. If the phone has more than one slot or tray, you can consider trying different slots.

Your Device Might Be the Problem
If the problem persists, consider using the same card on a different mobile device. Cards are compatible with any device that supports them.

Since the SIM card is made of plastic, it can easily be destroyed or deformed. The copper chip on the SIM card can also be scratched or broken. When withdrawing the SIM card from the phone, look at the chip and look for scratches. If your SIM card is damaged, your only solution is to replace it.
Phone updates are usually a good thing because they improve the phone’s performance, but they can sometimes also disrupt the standard functionality of the phone.

Contact Your Service Provider
