Roaming data competition must be heating up. I have found a few more interesting, beneficial things about Roamless to pass along.

1. Their rating on The Apple App store is a very respectable 4.7/5 with 2300 reviews. Android and iOS esim versions are available.
2. The service is portable between devices. You delete it on current device and install & log in on another and your service has been transferred.
3. You can obtain up to $10 of free credit currently due to a few offers. $1.25 free trial, $3.75 credit with coupon ESIM5 code, and $25 credit with $20 purchase.
4. If you refer another user who makes a purchase, you and the referee each get $3 credit. I created an account for my wife, and we both now stand at $33 for $20 each.
5. Most calls to Euro countries from US or Europe are billed at $.02 a minute. Canada is $.01, Mexico $.02. Others are higher. Some absurdly high, Cuba $.98, St. Kitts $17.68 !
6. In the US, you can select between T-Mobile or AT&T carriers. Outside the US, calls are billed at different rates depending upon fixed land line or mobile connected carrier.

My current status is, after getting free credits and building up my Forever account level, my US and also Euro data cost is right at $1.50 per Gb vs. the published $2.45 Gb.
I just ran a test using Pandora Radio App for about an hour & a half at the gym on AT&T, and my account went down $0.15.
