It is very unusual, but sometimes while traveling you can be in what we call a “fringe area” and you might lose Twigby's signal. You can check coverage in the area you will be traveling to at: twigby.net/checkcoverage.
If this happens, it is best to either turn airplane mode on for about 30 seconds and then turn it off or power your phone off and back on. When you do this, it refreshes your connection to the network and will typically lock on to one signal or another. This should get your cell phone service back by reconnecting to a closer tower. The procedure for airplane mode is specific to each phone. For more phone specific information, view our support section here.
Please note that troubleshooting connection issues are limited when in weak data areas and should not be performed when completely outside of data coverage.
