Total waist of money Total waist of money. Reception is extremely poor (used their SIM card in UK, Ireland and USA). My phone kept disconnecting and searching for network. In UK and Ireland sometimes I had EDGE connection (so the speed was so slow that I couldn't even send a message in a chat). Extremely disappointed.

Mystery on Signal Strength In my area (Pagosa Springs, CO) There are only two service providers with antennas; Verizon and AT&T. It is my assumption that the Telestial Passport SIM uses AT&T as a service provider since Verizon does not provide GSM service. I also have an H2O SIM card that definitely uses AT&T. When I have both SIM cards enabled on my dual-SIM phone (BLU Advance 4.0) the signal strength bar graphs sit side-by-side. The H2O signal strength bars show 3 bars consistently. The Telestial Passport signal strength bars continually vary from 3 bars all the way down to zero even to the point of displaying the "X" symbol. Since I'm new to Smart Phones, I don't know how to resolve this problem. Any suggestions?

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..

Sadly, not for me I really wanted this company to work. I purchased a SIM card for my travel to Italy, and was confused as to why I received a SIM card with a +44 (UK) area code. I have tried to enter the Italy area code before my entire phone number, removing the UK area code, keeping it, basically every combination I could create with my phone number, trying to make it work. I can make calls, but cannot receive them. My number simply never goes through. Essentially, I wasted a lot of time and money on a SIM card that is rendered useless. When I called Telestial, they were very polite, but of little help in solving my problem. Unfortunately, this is not the company for me.

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
