When unlimited pay as you go makes sense
If you stream on the go, use your phone as a hotspot or simply don’t want to watch a data counter, an unlimited 30-day bundle avoids the cost of buying extra data mid-month. If you mostly use Wi-Fi, a 10GB or 30GB bundle will be cheaper — see the cheapest PAYG SIMs.
