Best time to change tariff to avoid pro rata billing?

[Viewfinder]

As per subject - from your experience, when is the best time to switch tariff and have no or as little pro rata split billing periods? I have been on simplicity for a while now and it doesn't have an inclusive data allowance other than web daily. I could add a data bolt on but not sure if I an best switching to a similar tariff with inclusive or stay as I am with bolt on.  It will be very low usage for email etc and not for any excessive browsing!

I also want to keep to the 1 month rolling contract and not have to change this.  If I want to change tariffs and go for a tariff with a little bit of data such as the 100 or 300, when is the best time to switch without much of an overlap?

Granted that a change of tariff might incur some delay or overlap, I don't mind a day or so.  I have searched the forums and there are incidents of some double billing etc so just wanted some clarification.  Is it usually a day before next billing date or some time else?

Thanks!

Thanks Meri, just had to reply in order to check whether my options list shows Edit or not.

Still the same, no Edit... Here is pic if Lithium needs to see.

Not good @Viewfinder I am hoping this can be sorted. As I said earlier in the thread @Anonymous had this same problem and I think @Toby resolved that issue...I dont know how though?

Strange how some don't get that option on registration....

[Cleoriff]

And so annoying for newcomers. The option to edit is a lifesaver when you see you have made a mistake

[MI5]

I'd wager many don't even know that it should be there?

Its nothing to do with one's rank/experience here guys, we're just talking to some contacts in Lithium at the moment to see what the best course of action is.

Thanks @Toby Although I think the regulars knew it had nothing to do with rank and post count. It will be good to find out why. As @MI5 says...some newcomers probably don't realise they should have that option:smileysad:
