"maps is offline check your network connection" on Mobile Data Google maps is not able to connect when not on wifi, how to fix the problem? google-maps Kadin Schmidt 8 Months ago Answers 1 Subscribe Submit Answer Christiana Kovacek 8 Months ago I found out the problem. It happened after I put a secondary SIM card for a while and used it. Then when I switched back to the original Sim card while keeping the second one in, I didn't have a connection anymore. Seems it gets stuck trying to use the secondary sim card even if it's off. Solution: Remove the secondary card.
