Brillant First of all I called customer service to ask some questions before purchasing two sim cards, they were very friendly and helpful answering all my questions to my complete satisfaction. Ordered a sim card for my phone and one for my wife's phone 9/9/14 received within three days later 9/12/14. Excellent service. Looking forward to using my phone next month in England!... My wife will be using hers in Brasil!...

Great service I had some doubts to purchase a sim card prior to leaving for Africa. I had thought it easier to just get one there. Nevertheless, I did and got the "Explorer" SIM. It is a flexible, very reasonably priced plan that comes with both North American and Rest-of-the-World phone numbers. Of course, I checked out the SIM prior to leaving (NA number) and it worked perfectly. I recommend Telestial for your communicatiosn throughout the globe..

Telestial used to be a good company but … Telestial used to be a good company but they have changed. For us in North America we used to get a U.S. number with our U.K./Global number. They changed that so the US number is $2/month and they make it difficult to keep your balance active to. When they made their service change they said they sent us an email (which I never received) about my old sim being inactive and having to get a new one. There are better international mobile services out there. Telestial also refuses to refund my balance to me as well. Go with a different company.

Spotty cell service no data Currently trying to use the phone and data plan on travel worth limited phone success and zero data success. This means I'm stranded with no navigation tools in a completely unfamiliar city. After dark. Woman alone with my daughter. Not okay.

Utterly disgraceful, product and service. Stay away!! The phone was 2 days late. It didn't work, after a half-hour phone call with their tech support (who didn't sound the LEAST surprised). I sent it back. They said it DID work; they would send the phone BACK to me. I emailed them my mailing address; they said they never got the email. After another phone call (hold for 20 minutes), they said they'd mail it back to me
