Hi can you fit a wi-fi dongle on the Acer Iconia Tab A210 if so which one works
Hello and welcome to Android Forums, Chris!
Do you mean a USB Wifi adapter? I would highly doubt it since Android supports host mode for mostly storage only.
With app "PPP" works fine: E353 and MF112.
Tablet must be rooted.
Checked on t-mobile and three (UK)
Separate names with a comma.
