- I have a 3 PAYG SIM
- I loaded the empty (bar 1p) sim with 1 tenner credit
- I bought the 30 day internet addon for a fiver
I am off to france tomorrow and will have a play with it, but I didn't want to use the other £5.01 credit accidentally for data or anything, so I tried buying another internet addon, to see what happened. As it turns out, duplicate addons get queued, as shown below. Quite clever IMHO!
