Several years ago, people who switched their network from Verizon to T-Mobile were saying it was working just fine on the T-Mobile network.

Verizon, T-Mobile what is this?

We see about the iPhone, but we should also notice the names given above.

For example, in a country like INDIA, you can use many networks like BSNL, AIRTEL, IDEA, JIO, etc. but if once it locked with any network we can’t use another network until they unlocked it, like JIO.

Now coming to Verizon and T-Mobile are also the network carriers working with the iPhone. For suppose you purchased an iPhone 6 through the carrier Verizon, but now you want to change the network. So, the network you want to change is T-Mobile.

When you buy a JIO phone, the company itself locks with the same network. Like that when we are buying an iPhone, they also lock it with the above carriers.

Ok! That’s good.

So, now let us see the question.

But the question is, will the iPhone work in T-Mobile once it locks with Verizon?

Don’t worry it can work fine with T-Mobile. You can relax!

First, we will look at the general requirements needed when switching to another network.

1. legitimate device

The phone should not report as lost or stolen or associated with any illegal activity.

2. financial obligations

Your account needs to be free of any financial obligations. If you accept a contract for the exchange of subsidized up-front costs, you should wait until your contract is over (it takes 24 months).

Or your phone is through a payment plan; Thus, you must clear your balance.

3. Back up

When you switch to a new network before recognizing it needs to be factory reset. And make sure you’ve backed up.

For activating certain carrier accounts, it takes certain days before they allow to unlock.

For T-Mobile 40 days.

Sprint 50 days.

AT & T is to longest 60 days.

Verizon doesn’t have a minimum time.

Network bands

Before switching to another carrier, you should learn some information related to Verizon iPhone about its network bands.

GSM:  850, 900, 1800, 1900, 1700/2100 MHz.

CDMA:  800, 1900, 2000, 1700/2100 MHz.

the LTE bands are 1, 2, 3, 4, 5, 7, 8, 13, 17, 18, 19, 20, 25, 26, 28, 29.

These are network bands that Verizon will support. and it is compatible with 3G and 4G LTE bands belonging to sprint.

still works with AT&T, T-Mobile. But it misses three of the network bands in T-Mobile.

Missed bands in T-Mobile

3G & 4G (missing bands 12.66,71).

What is the process involved in changing the network from Verizon to T-Mobile we should learn?

Unlock process in Verizon:

A statement given by Verizon, in the device policy statement is “We do not lock 4G LTE devices, and we need no code to program them for use with another carrier. We do not lock  3G devices, other than our non-iPhone 3G World Devices.”

So, if you have a phone with 4G LTE services then it needs to be unlocked, or if it locked with 3G world device phone with verizon then you can unlock with code as 000000 or 123,456 or call 800-922-0204 for help.

Locking with T-Mobile:

Now you can simply call to T-Mobile network provider and switch on to that network and enjoy.


So, these are the requirements and process involved in changing your network from Verizon to T-Mobile.
