If you get the classic 321 PAYG SIM you can top up whenever you need to.
All calls, texts and data will come from your credit.

The only thing to remember is that you do need to top up at least once every 999 days and make a call or send a text every 180 otherwise o2 will think the sim is inactive and will close it.
Whcih is very inexpensive way of keeping your sim active @Kazzy803
