Many years ago i cancelled my landline in favor of a Huawei mobile wifi on Three and GiffGaff on my present .phone If i bought a new phone with 100GB or more on a 24 month contract and cancelled my Three WiFi. and GiffGaff would i be able to use my laptop by tethering from the phone.Hope this makes sense as my old braon is not very tech savvy.
whistonian, turn the wifi off on your phone and do a speed test. That way you will know if the speed is going to be fast enough for everything.
Whenever my wifi goes down I turn my phone in to a wifi hotspot and connect my pc and iPad - I get decent speeds of around 60 Mbps
Thanks everyone for your helpful replies. Barry I did as you suggested and although I have never had a problem with D/L speed I got a surprisingly low figure of 6Mpbs.
That is fartoo slow. Try it again and then again with a different speed checker. Try it in different rooms and outside.
I use this one https://www.speedtest.net/
