The process is simple... (digicel method)
1. Accumulate or buy $1000+ JMD worth of phone credit. Load them (topup) on to phone by dialing *121*CODES-ON-PHONE-CREDIT-VOUCHER/CARDS# for each card/voucher. You can purchase phone credit online securely with paypal and ezetop here.
2. Confirm your credit is above $1000JMD by dialing *120# (<--- CODE USED TO CHECK regular BALANCE)
3. Purchase/subscribe to international plan by dialing *134*1000#. Follow Instructions & Confirm International balance by dialing *134*1000# again after purchase is complete.
4. ENJOY DIRT CHEAP INTERNATIONAL CALLING... if you consider it to be about $15 bucks US for the 1000 minutes... then that's 1.5c per minute.
Cheers!
