I put my sim card in another phone and it won’t work

I put my sim card in another phone and it won t work, what is the reason why such happened, why is the solution to this very problem.

I’m here to explain the reasons why the other phone couldn’t detect the sim card along with a solution for you.

However, the first thing I want you to know is that there’s a high tendency that the other phone is locked or probably the sim slot is faulty, or maybe the network frequency doesn’t match the sim card.

Now let’s jump in to the question we have, i put my sim card in another phone and it won’t work.

I put my sim card in another phone and it won’t work

So let’s see the reason why such happened, and the solution to it.

1. The other phone is carrier locked

One of the major reasons why sim cards doesn’t work in a phone is because of the phone is carrier locked. Once a mobile phone is carrier locked, not every sim card will work in the phone except if the sim card is same carrier with the locked phone.

For example, the other phone is an AT&T locked phone and you’re trying to use a T-Mobile sim card in the phone, there’s no way the sim card will work in the AT&T locked phone unless you use an AT&T sim card.

THE SOLUTION 

In order to make the sim card work in the other phone, you should unlock the phone though it will not be easy for you as you have to meet with the carrier network to unlock the phone.

Once the phone is fully unlocked, definitely the sim card will work in the other phone and you wouldn’t have any reason to complain or ask i put my sim card in another phone and it won’t work.

2. The frequency doesn’t support the sim card

Another reason why a sim card won’t work in another phone is due to the fact that the phone frequency isn’t compatible with the sim card or the sim card doesn’t support the phone frequency.

It has happened to me when I bought a phone from Aliexpress, the network frequency isnt compatible with my sim card and even though it detected the sim card, I couldn’t make calls or browse on the phone.

This type of phone is usually called country unlocked phones cause it is only compatible with sim cards or mobile network in its country. Any other network outside the country will never work in the phone, and this is very common in Chinese android phones.

THE SOLUTION 

There’s no solution for this cause you can’t even fully unlock the phone, and I’m saying this based on my experience. It was really frustrating though in my own case I returned the phone back to aliexpress.

3. Sim slot issue

SIM slot issue can also cause such problem to occur in the other phone, maybe the other phone has a sim slot problem which you didn’t know about.

In this case, what you have to do in order to be sure that the other phone sim slot is faulty is by testing three different sim cards in the other phone, and if the phone is fully unlocked but didn’t detect the sim cards, then there’s a likelihood that the other phone sim slot is damaged.

In this situation you have to change the change the sim slot and changing a sim slot is very cheap than you think.

As long as the sim card is faulty and not damaged, these are the three major reasons why you’re having this issue of i put my sim card in another phone and it won’t work. 

Why won’t my sim card work in another iphone

The major reason why your sim card is not working in another iphone is because the iPhone is carrier locked, and the sim card isn’t compatible with the iPhone.

I gave this example, let’s say the other phone is an AT&T locked phone and you’re trying to use a T-Mobile sim card in the phone, there’s no way the sim card will work in the AT&T locked phone unless you use an AT&T sim card.

Once you have a fully unlocked phone, every sim card thrown at with will definitely work.

How to make a sim card work in any phone

To make a sim card work in any phone, you only need to have to have the every phone to be fully unlocked cause if the every phone is carrier locked, a sim card in another carrier network will never work in the phone.

I repeat again, there’s no way to to make a sim card work in any phone if the phones are carrier locked and not compatible with the sim card. You only need to unlock the phone in order to make any sim card work in the phone.

So if you’re looking for how to make a sim card work in any phone, I’m sorry but you need to have those phones fully unlocked or the sim card must be of the same carrier network with the locked phones.
