Sim card worked!!!! The sim card worked and the instructions were simple. I tried 4 different sim card brands and Speedtalk Mobile was the first one to actually work. When I called Speedtalk prior to buying the sim card, the customer service was terrific.

Easy to work with A SpeedTalk.com SIM came with the GPS dog tracker I purchased. By following the instructions that were provided, it was very easy to purchase a GPS plan and activate the SIM card. I also contacted them by phone and recieved excellent service. I recommend SpeedTalk.com GPS SIM card monthly plan.

Does what it says, good reception and data coversge Bought on line and was up and running in 3 days from ordering. Would highly recommend. Reception is great for both signal and mobile data. Been using for 2 weeks and all is good. Using in East Tennessee area.

Absolute garbage Absolute garbage. Beware, if you are trying to cancel your auto-renew, do it before 6 days before your plan should expire as they charge you for the next month anyway and will not under any reason, issue a refund, even if you talk to their supervisors. Do not use this company when there are so many others to choose from.

Beware of SpeedTalk scams I bought a prepaid SIM card to use for a month. They required a credit card to active and then "auto-enrolled" me in a monthly charge for service. When I noticed it they would not do anything about it, in spite of the fact that I had not used the service.
