Using A Data Sim In A 4G Tablet - Help!

[moggie 939]

When I was in Greece recently the hotels wifi was so bad I could not get a continuous signal on my tablet. I now have a new tablet which is both wifi and 4G unlocked and it has a place to put a sim card ..........I have a Vodafone PAYGO non smart mobile which I use here and overseas and it works perfectly for calls anywhere in Europe....bear with me I am elderly!

So if I purchase say a Vodafone DATA 4G sim will that mean that I will get a good signal for my emails and google search as I do in UK and what will happen if the area in Greece I go to has only 3G.? Does that mean that 4G will not work at all? I am confused - please explain in simple terms.

Thanks

Internet browsing on internet via 3g is adequate. I used to have an old SIM that the phone company forgot to turn off and I used it national and international without problems.

Wherever you are, if the 4G signal is too weak the SIM card will automatically connect to 3G or whichever sort of signal it can. Be aware of the cost as 4G can gobble up a LOT of data very quickly

Thank you both. hc4361...........so if my new tablet says suitable for wireless and 4G (there is a slot to put the sim in) does it matter which sim card I use? Can I put in either 4G or 3G card as I only use it on hols a paygo type would cost me less but I would have to buy 30 days data for my 2 week hols. I do not understand GB of data but if I am only going to check my emails daily and occasionally google should 10gb be enough?
Thanks again

10GB will be plenty. Put it in flight mode when you aren't using it and go for 4G

Thanks so much for that. I understand now. This site is really useful.
