Invaild sim error galaxy a40


Invaild sim error galaxy a40

I purchased a new mobile phone a few days ago - a galaxy a40.
The device was purchased in Germany.
When I insert the SIM card I need to press puk.
The code I received from the cellular company does not work.
The SIMs work properly on the old mobile phone.
How do I fix the problem?

Have you checked to make sure the phone is compatible with Sprint? You can do this at 


I can also look it up if you would like. If the device is compatible then you might need a new SIM for the phone.
