| Comment | Ive had a 3 sim for over a year that I never topped up (I had to do an initial top up) I think as long as you keep the sim alive its not normally a problem. If you plan on installing it then leaving it for 6 months offline then it will probably die, might get around it by popping it in a phone every month. Or just buy a cheaper £25 burner phone and keep it charged up. |
