When people deal with a carrier lock, they think they just need to contact their carrier (T-Mobile) and ask for a solution, and that they’ll receive a solution right away. However, sometimes, it is not that simple, and under some circumstances, you might require external help to complete the process. That’s when UnlockHere comes into action, as it is an excellent unlocking service that can help any user deal with this issue in no time. So, if you are one of those customers who want to know how to unlock T-Mobile iPhone through external means in case this carrier can’t assist you, you are in the right place.

The lock is a restriction that prevents the phone from connecting to other mobile networks besides T-Mobile. It only affects the SIM card, so if you use a different one from AT&T, Verizon, etc., it won’t be recognized by the iPhone. Many carriers use this to keep their customers with the same plans or just keep a registry of how many devices are connected to them. 

This can impact users in several ways since they will have to stick with their current plan (even if it is not that good) and also limit their connection in different zones and countries depending on the roaming service T-Mobile offers. The good part of this unlock process is that you can choose another carrier right away without reservations and use the phone freely with any SIM or cellular signal. 

Is it Possible to Unlock a T-Mobile iPhone that hasn’t been Activated?

It can be a tricky option, and you might need to use a different service. T-Mobile usually needs an active device to unlock it. This is part of the eligibility requirements, so without it, it might not be possible to unlock your phone as intended. In this case, the best recommendation is to activate the phone with T-Mobile, and if it doesn’t work, then use UnlockHere to remove this restriction. 

Eligibility Requirements to Unlock your T-Mobile iPhone

Eligibility Requirements to Unlock your T-Mobile iPhone

If you want to unlock iPhone devices with T-Mobile and use a different carrier, you must fulfill some criteria first. These unlock requirements are divided into two parts, one for prepaid and the other for postpaid. In this part, we are going to mention the general ones, and in the next, we will mention the additional ones for these T-Mobile plans. 

  • The device has to be purchased with T-Mobile. 
  • The iPhone cannot be blacklisted or reported for fraud. 
  • The account needs to be in good standing without a missing payment.

Requirements to Unlock Your iPhone Postpaid

Requirements to Unlock Your iPhone Postpaid

The unlock eligibility requirements for postpaid phones are more similar to the normal requirements any carrier would ask to unlock a device. For example, you need to have an active plan for at least 40 days that has to be paid in full (if it is leased or financed), and the account balance has to be zero with a canceled account. Lastly, they might ask for proof of purchase or any additional info related to the iPhone to complete this process. 

Unlock Eligibility for Prepaid iPhones

Unlock Eligibility for Prepaid iPhones

For prepaid phones, things change a little bit when unlocking your iPhone from T-Mobile, as you need to have at least one year with them. If not, then you need to complete at least $100 in refills during that time, and it cannot be less than 14 days since you purchased the iPhone. They might also ask for proof of purchase or any other data to clear the network restriction on your iPhone or other mobile device.

If you pass the unlock eligibility, then they should automatically unlock the device, and you don’t have to do anything but call them. The complete process can take two business days, and after that, it should be ready to use in another network with another SIM card. If they don’t remotely unlock your device, then they will send you a notification with step-by-step instructions to do it yourself and complete the unlock.

These codes can damage the device or give you security issues that won’t be covered by Apple or T-Mobile since this is not an official method that is regulated.

Of course, they are! Imagine that you are in a zone with a little town that doesn’t have T-Mobile coverage or that domestic roaming doesn’t apply. Then your phone won’t be able to connect at all! Unless you unlocked the device beforehand and got the SIM card of a small carrier to be connected and have mobile data again. This can also apply to international travel, as it can lock any possibility of connecting to a different network. 

What if you want to sell the device on Craigslist or Facebook Marketplace, and the users don’t want an iPhone locked by T-Mobile?

What if you have Issues Unlocking a T-Mobile iPhone?

The most common issues are that the SIM is not being recognized or that the phone was not remotely unlocked by T-Mobile, even if it is eligible. If that is your case for the first one, make sure your phone is compatible with that network or restart the device. For the second one, contact T-Mobile and verify their unlock policies, and if everything is correct, the agent can assist you in the unlock process.

If the code fails or the phone is already unlocked but doesn’t show it is, wait a couple of minutes, but remember to not try the code again, as it can lock the iPhone again. Restart the device, insert the T-Mobile SIM back, and then turn off the phone and insert the new one if it is recognized. Check that the tray is not damaged and that the SIM is in the right position; it should work after that.
