Nokia 1100 shows battery low even after full

it is not a sim problem
it is the problem if the batterry
you have to change the battery

This is your battery problem. Just do the step below hope it will solve a bit. get fully discharge and let automatically switched off. then connect to charging but do not switched it on after showing full charge, disconnect charging and switched your phone on. initially do dis 4-5 time a week. After that do 1-2 a week. This will increase your battery strength.......

if not then change your battery.
