Tried both MaxRoam and Digicel in Bermuda last week (liked the Bermuda day parade).
MaxRoam was more for comparison purposes. Still have to use *182*bigphonenumber# to dial out, but cost was only about a third of a Euro/minute from Bermuda to US, and I'll echo the sentiment that a free US DID number for incoming would be nice. Also noticed touchtone passthrough didn't work well although audio quality was clear.
Used Digicel for most calls back home (average 10/minutes day). International calls to US were more than MaxRoam at US 75 cents/minute, but easier to dial, easier to refill, and easier to be reached if necessary(same 1 country code as US although different country), plus local calls very inexpensive (free incoming from Digicel handsets, and other local calls only charged for first 3 minutes then next 30 minutes free for same call). Still a substantial savings over hotel phones, postpaid roaming or satellite phone calls.
