Internet dongle

[spottydog10]

My GF place a broadband order so she could work from home but with covid 19 this wont happen for a while.
BT have suggested a dongle so she can log on to internet using this one from Argos:

Argos wont deliver and I'm not happy with her going to the shop as she is in one of the at risk group.
My question is what is an alternative dongle that I can get delivered to her address, either fromAmazon, Ebay or the BT shop.
I note that in the 02 shop there is this:

Will this work on a PAYG basis and does it come pre loaded?
Thanks,
Mike

@spottydog10 The O2 link you posted says it works on PAYG. I can't guarantee it, but it should be preloaded and would just need activation.

Thanks mate, there doesnt appear to be any pre load information on the 02 dongle and there doesnt appear to be anybody taking questions on the 02 site.
I'd like to find a way to verify this before buying.
