I have a Samsung Galaxy SM-J260A and it won't pick up any service and the phones carrier is at&t and they can't help me

The phone is probably locked to AT&T; you will have to have your phone unlocked for any other SIM to work.

If you really believe it's locked to the AT&T network, that might be your only option.

If you got the device from someone you know who WAS the account-holder, they could assist in the completion of the carrier issues.

I'm guessing that's not the case, though.

I could but I have encountered this before and I have the "tech" know how to do this so i should be ok i just wanted to see if there would be a easier option then that

That is up to you. If you are tech savvy. However, if you make a mistake, that might make the phone more unusable.

I wonder if you could buy an unlock code from some ebay vendors.

Canadian carriers are suppose to unlock for free.

However, since AT&T is a US carrier, it has its own rules for unlocking. Unless you meet the criteria for unlocking, you might be out of luck.

This could be a bit of a pickle for you... where did you get the device?

Was there an AT&T SIM card in it when you got it?

Since AT&T are not bound by Canada's rules for device unlocking (being headquartered in USA), you may wish to engage in a telephone unlocking service available in kiosks in malls or other online-type services.

This may be a buyer beware moment...

So I gave it a try and they came back saying I was denied cause I don't have the account info for the plan or device

Sohpie91 · ‎05-01-2021

Ok I will give it a try

Use this service to unlock if it may be locked to AT&T

Unlock a Phone or Device - AT&T Device Unlock Portal (att.com)

Sohpie91 · ‎05-01-2021

I have done that but I have no clue where the phone came from so I can give them the right info to get me the unlock code

@Sohpie91 if the phone locked to its previous provider? (EDIT: as @Dunkman already posted previously)

Contact your previous provider to unlock it for you, at no charge to you.

You will need your imei number, dial *#06# to get it.

@Sohpie91

Are you a new customer? Just activated a plan? ported over a number?

Is the phone locked to AT&T? or is phone blacklisted?

You could try the SIM card in another working phone. this helps determine whether hardware issue versus Public mobile service problem.

The actual phone should be compatible with Public mobile.
