Before you grab your suitcase, contact Customer Care to activate roaming on your account. We’ll review with you your usage limit to ensure it’s sufficient for your trip, and you can increase it with an additional deposit.
You’re good to go. Your account is automatically deducted as you place and receive calls so there’s nothing you need to do prior to travelling.
When You Get There
Power up the savings by powering on your mobile phone. Select “Settings,” “Network,” “Manual Network” and “Roaming Partner.” In the US, choose AT&T; in Canada choose Bell, Telus or Rogers (if it's the only available option; Rogers currently doesn’t have data for GTT customers.)
If you need to call Guyana while you are roaming, just dial 011-592 followed by the seven-digit number, eg. 011-592-250-0000.
