Roaming and Q2501 Module


Hi, I would like to know if it is necessary to do any kind of adjustments on the application code to be able to work on Roaming.

Best Regards,



The operating will tell you through +CREG indications, if the device is registered on the home network (+CREG: 1) or in Roaming (+CREG: 5). If you don’t want to have different behavior in your application for those cases, you don’t need to make adjustments.

Best Regards,


However, be carefull, as GPRS roaming can be very expensive. I’ve heard of some very unpleasant surprises.

Use AT+COPS or some other operator selection machanism before You reattach on GPRS.
