Making A Call

  1. You must have credit on your account to make calls
  2. ALWAYS dial numbers using the full international dialling code (even if dialling in country or within the UK) e.g. +44 7624 xxxxxx (some phones may not need the + before the country code). Do not include any preceding zeros in the area code. E.g. to call a London number dial +44207 xxx xxxx NOT +440207.
  3. After dialling the number, there will be a short pause as the service rings you back to connect your call. You simply answer the call in the normal manner and wait to be connected. IGNORE ANY MESSAGES THAT THE PHONE MAY DISPLAY DURING THIS PROCESS. THIS IS NORMAL OPERATION

No call credit on your account

You may be dialling incorrectly

Make sure you do not add any prefix 0's before the country code or leading 0' on the area code. You MUST Always dial the country code you are calling, even if calling in country

Incompatible handset

If your handset is receiving calls OK it could be that your handset is not fully compatible with GeoSIM. Try dialling *125*1*countrycodeandnumber# followed by the send key. Remember to use the # key at the end.
