One potential cause of call-related issues could be compatibility, especially if you’ve recently inserted a physical SIM card and restarted your phone. Allow a few minutes for it to activate and connect to nearby cell towers.
If your phone prompts a carrier update, complete it for proper SIM card programming. Also, check your coverage area for call problems.
If issues persist, even in areas with supposed good service, contact our Mobile Customer Care team at 855-811-5188. They’ll help resolve the issue and ensure optimal phone functionality for calls.
