No WiFi & almost at giffgaff tether limit :'-(

[#1]

Hi

I've been using my giffgaff Always On goodybag to tether to my laptop. It's the reason I bought the goodybag, but have just discovered that tethering use is limited. 

Recently I moved far away from all my friends and family and feel isolated. Trouble is I cannot install WiFi here (certainly not for the foreseeable future). I previously used e-mails, twitter, podcasts, periscope & sometimes face to face voip.

Can anyone please, please, please advise how to get online & stay online? 

E.g. if I purchase an 'O2' dongle to use with a giffgaff sim I'm worried I'll still have the same thethering limitations 

Thank you for your help
