Can telna Mobile be used for cellular service inside the USA?
While telna Mobile technically works in most areas of the USA, the service is not meant to be used for placing or receiving calls inside USA, as those calls will be charged at very high rates. For your protection calls from within the US are forbidden by default on your telna Mobile SIM card. Please ensure that you remove your telna Mobile SIM card from your telephone immediately upon your return to the US to avoid accidental charges. Other countries such as Canada or Mexico have very high usage rates due to restrictive roaming agreements. Please make sure to always confirm the rate prior to using telna Mobile in any country.
