"When using the 10GB tariff the E169 device will only connect when receiving a 3G or HSDPA Signal, however your 3 Mobile handset will allow you to make calls when in the 2G Signal areas. For confirmation of you signal coverage please visit our website at www.three.ie and select Coverage or call our Customer Services team."
