Adding data to an iphone 4s

[rlbbla]

My kids gave me a used iphone 4s.  I was using it without data, just for calling and texting, but a couple of days ago I added a month's worth of data just for while I'm on vacation.  I can't seem to get it to work.  I've gone to settings and I've got Cellular Data turned on.  I've tried what it says on the Telus website -- plug it into itunes.  And it says it needs an update but the phone itself won't do the IOS 9.2.1. update.  What else should I do?

You will need to connect to wifi to update to 9.2.1, it can't be done over the cellular network. 

Confirm with Telus that there is not a data block placed on the account to prevent data consumption.

You may need to go to Settings > cellular and turn on data for each app.

I'll see if I can add any more info in the morning. Edit - the above pretty much covers it.

@ribbla: To clarify....

• Where are you travelling on vacation? A local stacation?  Or roaming internationally?
• Are you on a prepaid plan?
