I installed a few verizon roms. I can change the network setting, but always get an error when i search for net works.
I only have 2 sim cards to test it out so I am not sure if there are bad sims. One is verizon LTE and onther is from an overseas gsm carrier tigo.
What more can I do with out bricking my phone?

I added some screen caps.

I finally received the part from china. I installed it fairly easily. I did have to cut the back cover and pat of the metal plate from the reader.

Sd card works and reads fine. I only have have a verizon LTE and a tigo sim card to try it out So I am going to try flashing different roms soon, I am on Blazer. Nothing seems to happen when the verizon sim is inserted.

you are still be able to use sprint LTE, since the sprint sim is built into the main board and not the sd/sim reader.

Any have advise on how i can check if it know a sim card is inserted?

I was searching ebay for parts and I found this.



It should be as easy as unplugging the old one and plugging in the new one. You would also need to get a verizon back plate. But this phone is super easy to open and change parts, minus the screen.

You will lose LTE, unless there is some way to get a sim from sprint (the Iphone 5 has one).

Does anyone know a res eon this will not work? I plan on ordering one later today.

Thanks

I live in Serbia (Europe) and just got this Sprint Galaxy S3 from USA.
Several members here said that when thay just poped in SIM card slot that thair phone didn't turnet on. So I was just wondering what did you do before you puted sim card slot in. Other members said that thay birked thair phones by instaling international ROM...

Any updates on converting CDMA to GSM I have a sprint sph-l710 and want to attempt to convert to Verizon. I do believe Verizon uses CDMA.

this convert will be a tough one but i think in 2018 we will be able to do it

I accidentally removed the Sim Card from the back of my Galaxy Tab 3 tablet fro Sprint, I though it was the slot for the memory card. I now can't not put it back. Does anybody know how to do about it. I of course can wait until the stores open, and have them do it for me. If you response to this I would appreciate it , if not, I will do it when they open tomorrow or Monday.
