Misinformed The Ireland & Europe SIM Card does not work well in Ireland. It works in the cities in Ireland but not in rural areas. Telestial Inc. should be aware of this and inform potential customers. My sim card only worked in cities and I had no coverage outside them. In an emergency you would be stuck for want of a connection. Telestial Inc. should refund me the balance on my account, if they are a company that operates in good faith.

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.

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..

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?

Super fast and easy! I'm headed to Europe for the first time for a month, and figuring out how to call home was a massive headache - do you use your provider, buy a SIM card there, illegally unlock your phone...? Telestial was a super simple solution. We ordered the SIM card online, and it arrived within two days with a TON of information on how to set it up, how to top up minutes, etc, in a handy pamphlet that fodled up to be wallet-sized. Very useful, very straight-forward. Highly recommend!
