I have just unlocked lumia 1020 but there isnt signal
I have an AT&T branded Lumia 1020 that has been sim unlocked with the IMEI code. I insert my claro sim (peru network) but no signal or any bar (disabled). Before I had 2 lumia 920 and 1020 both AT&T branded unlocked and is the first time this happens to me and I can not make calls or access the Internet with my data plan.
I don't know if this will help but go to the Settings then Cellular then Network selection and choose manual and find your home network. Might help as I had similar issue with different phone. You might need to put the APN settings manually.
