I'm currently using an international sim, with a web data bolt-on of 500MB. I have to top up on the 15th of every months so I can get data on my phone.
I'm going abroad on Dec 14th and coming back on Jan 27th. During this time, I won't be using my o2 sim. My question is, if I top up with enough money to cover the date bolt-on when I return (Jan 27th), will the web data be activated? Or do I need to top up on Dec 15th, and on Jan 15th so I can keep my data bolt on?
