Take phone, place in microwave on low for 5 mintues. Will unlock it and charge the battery as well at the same time.

There's no way this could be serious. If so, I'd definitely find an alternative lol

Were CDMA.

 

Google it.

 

Our phones don't unlock - we don't use services like that.

Question #4

Maybe I'm reading the answer wrong, but my phone has a SIM card.

All US Cellular phones are CDMA and are able to be unlocked. They will not work on any GSM network. You can only unlock it to be used on other CDMA carriers that will allow another carriers phone to be used on their network.

 

(i.e. Ntelos, Cricket, Straight Talk, etc)

 

Some US Cellular phones are world phones and can be used on GSM networks outside the US ONLY.

 

The SIM card and SIM card slots on U.S. Cellular phones are for LTE ONLY - they DO NOT work with ANY GSM carrier in the U.S. They also do not work on any carrier other than US Cellular.

 

There is currently NO WAY to "unlock" or "hack" the firmware to allow use of GSM carriers.

I know it has a Sim card, but the lte Sim we use and a gsm networks Sim aren't the same as far as purpose.

The Sim for us allows data connection, whereas a Sim for a gsm carrier is essentially the programming of the phone. For service in general, not just data.

So our Sim won't do anything in a gsm phone, and their Sims won't do anything in ours. Our phones have the programming already built in.

If you are on AT&T there is the unethical, but effective way of doing a support chat online with AT&T, tell them you have a funeral in Europe, you're traveling there and need to unlock your phone for a European carrier. They gave me the code and told me that it was unnecessary for non-AT&T Sim cards but would allow the use of other AT&T Sims. It worked.

So...wait.

He has an att S4, and wants to know what carrier to go to and keep the phone?

There's only two primary options att or tmo. Cut and dry.

It will never fully work on USC or vzw - no matter what. Were not the best choice of opinion since were the polar opposite type of carrier.

What confused me was where the other says "we don't have a SIM card to switch into another unlocked phone, and I knew mine had a SIM, just wasn't sure if it would work for what the OP is wanting.

:wipes forehead:

 

Sims (in regards to USC) are not interchangeable. In any way.

 

USC sim to USC phone only.

Att Sim - USC phone - no

Tmo Sim - USC phone - no

Vzw Sim - USC phone - no*

USC Sim - tmo phone - no

USC Sim - att phone - no

USC Sim - vzw phone - no

 

It doesn't matter that you have a Sim, your Sim slot doesn't work the same way - sadly - but you're stuck picking a gsm carrier, tmo.

 

You might get some things to work, but others won't, and likely never will. Same with us, we can't use gsm carriers as normal.

 

I wish this wasn't true, I wish that unlocked devices were 100% universal and you could pick any carrier, Sim or not, but the US has taken away that monopoly option. Which, I get, but don't necessarily agree with in its entirety.

 

I wish my phone would work in other countries without having to roam, just pick a prepaid for the trip and viola, that would be easier.

 

*requires illegally swapping ESN numbers.

I have not heard much about the site that you have mentioned...

As to my experience i unlock phones with the help of Simpleunlocking.com where they provide you with unlock codes along with free instructions to unlock your Samsung Galaxy S4...

That only applies to GSM phones.

USCC is a CDMA carrier. Two entirely different technologies.
