the new 10.2-inch iPad looks not bad. screen looks good despite as usual non-laminated but bigger display with slight thinner bezel than before makes it look more worthy and nicer. As compare to iPad mini, the bezel is not extremely thick like before.

Really good iPad for everyone especially for elderly or kids who do not need professional function like iPad Air or pro.

My mum's Ipad 2 needs a change. It's getting really really slow with iOS 9.3.5. Guess this 10.2 should suffice?

For normal usage should suffice, both my parents are happy with it now.
My sister was complaining that the Facebook app auto logs out my mum's account and she has been helping her to key in FB password every now and then. Not sure if it's the app, iOS or iPad issue. I don't think it's human error as my mum doesn't know how to logout.. I asked her to uninstall and reinstall the app, hope it will fix the issue.

Also another issue which I ebcounter, though I have activated fingerprint verification for apps download but it will still prompt to insert password. It's really annoying. What's the issue?

yes, cannot calls and sms at all. only can iMessage and Facetime using apple id (email address).

Wifi + cellular model allows you actually the same Internet acivities like wifi model using sim card to allow the convenience on the go. Wifi + cellular model also comes with built-in GPS unlike Wifi only model.

The 10.2-inch iPad is ideal for elderly and kids.
There is a rumour that the 10.2-inch iPad may get upgraded to 10.8-inch and with A12 chip (same chip as the current iPad mini and iPhone XR/XS/XS Max. Though it is a old chip but it will be quite significant upgrade from the current A10. However, being a rumour, no one will know whether it will really happen, so if you need it urgently now, then it may not be relevant.

Yes, my mum uses it for YT, Astro Go, Tonton and online newspaper.
Despite we have Astro at home, sometimes she wants to watch other channels.

Great battery life as well, so cannot find any fault in this model.
Yes, you can. I don't think there is telco-locked anymore these days for devices (except routers from some providers).

So does that mean that the number is locked with the ipad?
