I bought a Huwaei (unlocked) and use '3G' pre-paid sim cards.
The later model Huwaei has provision for an external aerial.
Many people "tether" their mobile phone and use it as a router.

Read the Amazon reviews about using it abroad.

Have you searched CT Roger, there's a whole heap of threads on it.

It does the same job Roger, probably better,
with its external aerial. There are lots of pringle
can adapters to mess about with and wifi enhancers
but I know mine works(and it can be used in France)

Which one? I might just need one as well as my WiFi signal is a touch on the weak side out here in the Atlantic.

I thought there was that much US gear on the seabed that you'll be able to pick up Eastenders in mid Atlantic.

I have been using the Three MiFi for wireless broadband connection for some time now. Because it is wireless it can go on the roof of the Eriba in a small waterproof box or bag if the local signal is weak. We have not used it abroad because we try to use campsite or shop free wifi although I believe you can use a local SIM card.

we ended up putting comp on thick book on hob tup with kitchen window on night catch, it was the only way to use the free wifi in the eriba, slight movement of comp, lost signal completely. the dongle was very signal movement sensitive, until I opened another window.
the blinds seem to restrict if down as well
thank goodness for wireless mouse
faraday cage spring to mind

I just hang the Huawei up by the pop top canvas (inside of course,
no Faraday effect and quite a high point) as I said the more recent
model will accept a plug in external aerial.

And comes with a Chinese government assistant as standard

The price they charge on some sites I don't really want it...................anyway its nice to get away from all that on holiday sometimes I usually only take the laptop to download photo's and edit \ delete unwanted ones and to play games on it in the evenings if there's nothing on the telly.
