I was putting this in another thread, but thought it might be useful not to be burried... so here's the digicel codes that I know of (feel free to add to it! :) )
Check credit balance - *120# Send
Check "bonus" minute balance - *120*4# Send (right now they have a promotion for every paid minute you talk (not intl. plan minutes) during the day you get a free minute to use between i think it's 11pm and 6am (might be 12 and 6)...
Activate International Plan (1000 minutes for a month for 1000J)- Add 1000J and *134* Send, wait for text back with instructions... will tell you to txt *134*1# to confirm (or *134*9# to cancel), just follow the instructions.
Check International Minutes - *134*10# Send, wait for txt back with balance/expiry... (works once above plan has been activated)
if you have less than 5JMD credit you can send a "please call me" txt to someone (you get 20 of these a month i think)... to do this you dial *126*1xxxxxxxxxx# (where xxxxxxxxxx is the number of the person you are sending it to)
Hope that helps somebody :)
