I have visitors with teenage daughters who need wifi. I've already mentioned the mini market and Hoya 19 but wonder if a dongle might be a solution. I used to get mine at PTT (I think) at Vila Real but am wondering if that is still the best solution for short term access.
Any advice appreciated.
Thanks

If you have more than one Wi-Fi user then purchase a MIFI (hotspot) hub in the UK before you come (Amazon or Maplin) - (might be an idea to get one with an aerial socket in case your not in the best signal area).

AFAIK the best signal strength in CE is from TMN (MEO) - you can get a 3G SIM for 9,95 euros which come with 10 hours free. It costs 1 euro per hour after that. The TMN (MEO) shop is at the top of the pedestrian main street just round the corner on the left.

Make sure you get a Banda Larga SIM - they sold me phone SIM for my dongle and it was a hell of a job prising a refund from them.

The advantage of getting a MIFI hub is that you can put a different SIM in wherever you may be and whichever provider you can get the best signal and deal from - see if you can get a 4G compatible one so you have a degree of future proofing - unfortunately that is not always guaranteed - as has been exhaustively discussed previous on the forum

Thanks Mike, I have passed on your recommendation .
