I am on my 5th (approx) 24gb 3 data sim over the years. Example. This year we have had 3 trips to France, Spain and Portugal.
1 x 7 weeks
1 x 2.5 weeks
1 x 3.5 weeks
Also various trips of up to a week in Rep of Ireland and use in Uk (N. Ireland) on all other trips which in total makes this years count to about 120 nights (more if you count the days at the end of each trip)
I have always got the full 24 gb, in fact then sim usually starts with about 25 gb when activated. The current sim in use as I write is down to 11955 mb. I have another 2 sims in a drawer which will probably cover me for another 2 years or so.
My take on it is that my style of usage does not trigger any restrictions. I only e mail, surf forums (about 9) each night for up to 4 hours and read online newspapers (3), weather forecast, route plan, search fo pr sites etc. The only concession to streaming is an occasional Skype to the daughter in Australia.
I also ensure that I turn the
mifi on to establish a connection on return to the Uk. As can be seen from above, longest trip is about 7 weeks which possibly helps.
