Howdy deshwasi. I'll be more than happy to assist in getting this phone unlocked. I sent you a PM so I can gather a smidge of info.
I received your private message also. Please review my response for the needed information about the phone.
Hello I'm having the same issue, just received a new unlocked phone and phone keeps saying invalid sim. The is the same model and the sim was working in my previous phone before it suddenly became a paperweight. Please help!!
Good Morning bstrickland5! I just have a couple of questions to better assist you:
I have a sprint galaxy s7 edge and I am trying to put my SIM card in it from my iPhone XR but it keeps giving me the invalid SIM card notification. But i was told that it would work
Like I mean if I wanted to take my SIM card out of the iPhone and put it in the s7 for awhile and switch back I can’t do it with just one sim
Howdy bstrickland5. The sim cards are designed specifically for the phones they are used in. If you wanted to go from a Galaxy s7 to the s8 then you might be able to switch the card between the phones. iPhones are a smidge different. most of the time they can't be switched between iphone, and I've never seen a sim card from an iPhone work in a Samsung device.
A new sim card can be picked up at one of our repair stores, can be ordered online, or through our telesales department.
I'm having the same issues, I've spoken to Sprint twice and they told me it was unlocked, however when I put a new sim in it tells me to contact Sprint which I am then told the same thing.
