Most GSM handsets offer a choice to select a new network, automatically or manually. The default setting, in most cases, is automatic, which instructs your mobile to automatically connect to the strongest network signal available. As you move, the handset will continually monitor the available networks, and keep you connected to the strongest one. In a manual network selection setting, your mobile handset will detect if there is more than one network present and offer you a choice. If you then select one network, your mobile phone will remain connected to it regardless of the alternative networks available. You may prefer to remain connected to one network if it offers cheaper outgoing call charges. To manually select networks please refer to your mobile phone user manual for instructions. Your Jersey Telecom SIM card can store a list of your preferred roaming partners. If you have an automatic network selection setting, and there are two networks of equal strength available, the mobile phones will connect you to the one that is highest on your SIM card’s preferred list. The list can be edited by using the appropriate menu on your mobile phone. Check your mobile phone user manual for details.
