Yes, sorry, I was thrown a bit when you said dongle and rambled on about usb. Yes the MiFi is good I use the Three network with my mobile as router and it works great but........... ......You say you are going on holiday. If it is abroad be careful of data roaming charges. The hotel WiFi would be better. At home the MiFi would be good. What are your reasons for wanting it? There may be other options.
