Yesterday TelnaMobile seems to have suffered a roughly 12-hour crash. During most of the day the phone would not register and I could not access their website. Then it just started working again. So far, there's been no explanation.

Message #60 has a perhaps answer. Start reading from message #55 until the end of the thread. This is about Piranha Mobile which uses Telna NA as its USA MVNO [including its roaming relationship with T-Mobile, I suspect.] I don't have Telna, but I do have Piranha and both the descriptions sound like what happened to me. [I did not have trouble with Piranha's web site. ]

A recent change in the way that the Telna SIM connects means that, in direct-dial countries (e.g. US, Canada, Australia, etc.), the cellular data feature works, regardless of the phone's APN settings. You need to turn your phone's data off and not rely on a bogus APN to prevent data charges. Fortunately, this lesson only cost me about 50c to learn.

TelnaMobile charges
 

I just want to mention that TelnaMobile charged my credit card twice for the annual $19 fee. I called them, but they cannot credit my credit card. , they can only issue an account credit. So, I asked the CSR to go ahead an do that. I will try to use that up when I am in Nigeria next week. Even though I have a couple of local Nigerian sim cards. I have not even used the sim in years. So, the $38 annual fees + taxes came to $51. Insane taxes in Illinois. Time to deactivate TelnaMobile. LOL!

I also noticed that the USA rates are not viewable. Here is the message when one checks for USA rates "Please contact our customer service to check the rates for USA."

I gotta say that not being able to credit your account is bogus. I'd call my credit card company and tell them the story. I bet you'll get your refund.... I have to admit that I'm a bit down on the international sim game. Becoming too much work to experiment on each trip to see if the sim will even work...

I will contact my credit card folks tomorrow. I agree. It makes no sense. I really no longer have a use for the sim card. I'll deactivate it once I resolve t this issue.

If you wrote them, citing the Fair Credit Billing Act, explaining the double billing, they would have to figure out a way to credit your account.

Update - I called them back and ask that they credit my credit card. They did go ahead and put a request in for that, and I received an email confirmation.

Telna customers being switched to G3 Telecom of Canada
 

There's a pop-up note on the Telna Mobile home page that customers (not sure if all or just long distance customers) will be switched to G3 Telecom of Canada effective January 1, 2016.

I had Telna Mobile for a while and liked their rates, customer service and postpaid credit card billing (in the past I have occasionally gotten burned on some prepaid roaming sims that bit the dust). But a few months ago Telna rates went up for US, Canada, Bermuda and some other destinations. Cancelled my sim card as result since their new rates were higher for these destinations, and I have other alternatives such as prepaid country specific sims, InMarSat prepaid and SIP/VOIP.

G3 Telecom apparently has good reviews (at least the Better Business Bureau gives them an A+ rating). Know someone else who still has Telna Mobile and wanted to know other people's thoughts on this change in service. Thoughts anyone?

Have not been back to their website since I cancelled my SIM a few months ago. I just did not have a need for it, since I also have Piranha. You are correct - I did notice an increase in their rates the last time I checked.
