1. About GSM and the Mobal GSM SIM card

The worldwide GSM network

The GSM network (Global System for Mobile communications) is the most widespread mobile network in the world. In order to use the GSM network you require an unlocked GSM handset (which is compatible with the local cellular frequency where you will be using it) and a SIM card.

The Mobal GSM SIM card

GSM phones require a small electronic chip, called a SIM card, to be inserted into a slot in the handset. This SIM card is the “heart” of your phone – it contains your mobile phone number, your phone book, and all of your registration information. The Mobal GSM SIM card provides you with access to over 320 GSM networks in over 160 countries.

Your GSM handset

All current GSM handsets should be compatible with the Mobal GSM SIM card. However, you should check with the supplier of your handset that there are no SIM card restriction locks in place. Also, you must check that your GSM handset is of the correct frequency for each of the countries that you intend to visit. Most of the world’s GSM networks operate at 900MHz and 1800MHz. However, in order to use the networks in the USA and Canada you will need a handset that is also capable of operating at the 1900MHz frequency. Please refer to the Mobal GSM Country List/Call Rates for details.

How to insert your Mobal GSM SIM card into your GSM handset

Carefully remove the small SIM “chip” from the plastic card. The method of fitting the SIM card into your GSM handset varies with each manufacturer. It is usually a simple process of inserting the card into a slot on the back of the handset, often under the battery. Please refer to your handset’s user guide for details.

How to Access Voicemail

To access your Voicemail messages please dial  901 from your Mobal  phone.
