Manual
a) Who can avail this Service?

Every Comium Postpaid Subscriber can enjoy our Roaming Facility

b) How to select GSM network when abroad?

Any Modern GSM handset offers a choice to select a new network, automatically or manually. The default setting in most cases is automatic. This setting will instruct your mobile phone to automatically connect to the strongest partner network signal within reach. As you head towards your destination, the handset will continually monitor the available networks and keep you connected. In the Manual selection setting your GSM handset will detect if there is more than one network present and offer you to choose. Choose the network and get connected without any hassle. To manually select the network refer to your mobile phone user manual.

In case of any difficulties in getting connected to Comium listed Roaming Partner Call +2206601111
