WHY BUY our OMNISIM INTERNATIONAL SIM CARD? Compare and you'll soon see why!
1) We do NOT use INTERNET PROTOCAL (IP) for calling as so many of our competitors do. IP quality is notorious for call failures, disconnects, terrible sound quality and outrageous noises and disturbances of all kind. IP on a cell phone is NOT like VONAGE or SKYPE etc. whose service quality is far better. We use ONLY the best service providers in 10+ countries and have contracts with 450+ service providers to virtually guarantee excellent service in our covered countries.
2) Our OMNISIM international sim card gives you a tel. # based in the UNITED KINGDOM, not Estonia or Liechtenstein! Be very careful when reading our competitors' ads as when they hide the country in which their sim card is based its for a reason and when the rates are lower than our rates its because they are using IP and not legitimate CELLULAR SERVICE PROVIDERS around the world. Calling a Liechtenstein cell phone number usually costs twice as much as calling a UK cell phone number and calls to an Estonian number can also cost nearly double.
3) Many of our customers pay only $0.25 per minute to call from the USA to our OMNISIM card by using this company:

When signing up, use the code QST647 to receive a free trial with up to 120 free minutes of International Calling so you can start calling immediately! Visit their web site, or call them at 1-800-881-3004.
and many purchase CALLING CARDS which can cost as little as $0.00.9 (9/10th of a US cent) per minute.
So we are proud and delighted to tell you about our services. Best quality calls, lowest rates and for friends and family in Canada or the USA wanting to call you they will save every time and every minute when they call our UK based (country code 44) OMNISIM card number.
We truly have the best of all worlds.
