The following is a sample of a telco prepayment using USSD:
Retailer SIM to Prepaid SIM
224#Prepaid Sub Mob Tel NoAmount*PIN# then press SEND or OK
Press Answer Key then
Press 1 to continue or 2 to cancel
Example: 224#9229225150150*77777# then press SEND or OK
Press Answer Key then
Press 1 to continue or 2 to cancel
This works fine with an ordinary cellphone. Using a Wavecom gsm modem (with SAT enabled) will give a negative result. (+CUSD: 4)
Using a cellphone and dial 224#9223424148150*00000#, the telco will send a message saying: YOU HAVE REQUESTED TO LOAD 150 PESOS TO 09223424148. PRESS 1 TO CONTINUE OR 2 TO CANCEL. Then I’ll press the Answer button at the lower left of the phone screen and I’ll type 1 to send. There will be a confirmation afterwards.
That message doesn’t appear at all if I’m using the Wavecom gsm modem. I think I’m missing something here.
Please I need help on this.
Thanks and regards.
