Our rural church has a contactless donation device that needs a 3G data connection to function. It uses less than 200MB per month but will provide the opportunity for visitors to make small donations. We really need a cheap data SIM with a long expiry on it so that the costs of the SIM do not use up the value of the donations. What should we use? For info, we do not have a landline, broadband or wi-fi access and could not use a tethered phone because of the risk of theft. Vodafone is the only carrier with 3G coverage in the area.
