Telecel Zimbabwe has introduced an emergency credit facility for active pre-paid customers, allowing you to run out of airtime and still use your phone.
If you are a Telecel subscriber out of airtime, dial *143# to obtain a dollar’s airtime on credit. Once you recharge the dollar a 10c charge is deducted. Intended for emergencies, once users have spent their bottom dollar they cannot receive another dime until they repay their debt. To qualify, the subscriber must have been an active subscriber for at least 90 continuous days.
