There is moderately good cell phone coverage on the treks. Especially in Sapa. In case of emergency, there is usually a fixed phone in the Peoples’ Committee Office in the nearest village. If you are still concerned it is recommended that you rent a satellite phone in your country before coming to Vietnam. Please make sure that you know how to use it and that you show your guide how to use it as well.
