GMPCS Personal Communications

I signed a two year contract marine satellite communications for my yacht, VSAT and VOIP, with GMPCS. The VSAT service did not meet the minimum guaranteed speed for the first 18 months of the contract. GMPCS Tech support kept telling me it was the hardware, and every hardware technician ran several tests, and said it was the GMPCS service.
I was paying for two telephone lines (VOIP) but only one worked for nearly the full two years.
For over one full month in 2012, we could get no VSAT service at all. GMPCS was no help, and we had to fall back on our FBB for tech support, which cost us thousands of dollars.
GMPCS refused reduce my bill for the lost service, or allow me to terminate service. They used a clause in the credit application to start billing my credit card without my permission, rather than talk to me about how unhappy I was at getting billed the full amount, even though I was only receiving a fraction of the VSAT speed they guaranteed, and only one half the working phone lines I was paying for.
They did get my service speed up to the guaranteed minimum about 3 months before the end of my contract, but refused to let me turn off the service when I put my boat in dry dock. Continuing to bill my credit card directly after I had made repeated attempts to turn the service off, and several requests to send me bills so I could see what they were billing me for.
My experience with this company was universally bad. They were totally incompetent at delivering the services I was being billed for, and hypercompetent about taking all my money and more. However, they reverted to incompetence when it came to terminating the billing.
They cost me a lot of money, and time, for a terrible level of service, far below what they promised.

I Recently purchased the new I-​sat phone for an upcoming trip to the outback.
if you need to be reached in the most remote places on earth. A sat-​phone is a must have gadget.
Make sure to see Dexter in sales. i purchsed my phone from some woman on the phone who didnt know much or cared, but when i met dexter and the follow-​up service and training he provided to me on the usage of the phone was incredible. After you plunked down alot of cash, the professional and expert customer service dexter provided made the purchase well worth it. Patrona, the sales person i dealt with please take a note, you need to follow-​up.
I had issues with my overseas sim card, and it was resolved within 24 hrs. with a brand new one, fedex to my door. Dexter had performed extensive tests prior to the phone with a pre-​paid company sim card. the sat phone worked well as promised when i walked out the lobby. when i got home to try test the sim card that was new and unopened, it did not pass. no problems, called dexter that evening and sent me a new one, 1000 miles away in the remote mountains of West Virginia. After my work was completed there, i flew international via united, which is another review, yo a remote desert in Southeast Asia and it, functioned excellenty, you can text and it can send your gps position to loved ones.
