Very Poor experience . Worked ok in England but hopeless in Ireland. Lots of trouble shooting and emails but no luck. Changed back to my primary sim and worked fine. Very disappointed with Jetpac.

The good news is that most newer devices now support eSIM technology, so you can have the convenience of not having to change SIM cards when you travel.

On the other hand, if your device doesn't support eSIM technology, then a traditional SIM card is the best option.

If you need SMS and phone calls, look at the SIM card provider and see if these features are supported. Sometimes, eSIM providers offer them, too - but it's quite rare.
