I am not using the phone now. Is this the reason why I missed the signal? What should I do? Should i
put the SIM card with sprint back to the phone?
I've got Samsung j3 from my friend for last year after back from USA, but it's locked. is there any possibility to unlock the phone?
Hi anakancil. Please check out the link below for the unlock policy. If you believe you qualify, you'll need a Sprint SIM so we can send through the signal once we validate the device is in good condition for an unlock.
Drop me a response if you've met the requirements and have a Sprint SIM and we'll go from there.
