Mobile network coverage on Kilimanjaro has improved greatly over the years. Signal will be available for almost the entire climb to the summit but it will be very inconsistent. It means that at certain segments on the trails there will be disrupted connection or no signal at all. Since there is no mobile charging option in the camping tents, except for your personal power banks that may suffice for a few days, we suggest you to leave your phone on airplane mode. This will avoid your mobile to constantly search for cell signal and drain out the battery unnecessarily. Ask your guide which spot is likely to receive network coverage or watch your porters use their phones to confirm that the area has cell signal so that you are able to send or receive messages or calls. Whenever you receive network coverage, don’t expect the signal to be as strong as it is back home. Forget streaming data and also stay aware about the data roaming costs the local cell phone companies will charge.
