This could be because of an invalid mobile phone number or a technical error. Please check these and then try again:
- Verify that you have entered a mobile phone number which can receive SMS
- Check that you are currently within network range
- Check if the country code of your mobile phone number is correct. Use the following format, for example +60 xxxxxxxx for Malaysian phone numbers
- Restart your phone
If you still don’t receive the verification code, please contact customer support at Grameenphone.
