iPhone 5 US Sprint Locked – R-SIM 10+


I have an iPhone 5 locked to US Sprint and recently I bought a R-SIM 10+ card.

I live in Romania, so I use Telekom Communications Provider aka Cosmote. When I inserted the r sim and the sim card I chosen US Sprint provider and then I selected the unlock method: GSM Mode 2/3/4G because my provider uses GSM Network. All worked fine and activation was successfully done but it’s stuck on searching even giving me invalid sim.

What should I do? I tried also to use IMSI from Telekom(Cosmote) which is 2260307 but also didn’t worked for me.

I hope you give me some solutions and get this to work.

Thank you!
