I have family who live in Spain and are struggling on the broadband front in recent years, Telefonica adsl speeds have dropping over the past few years to levels where streaming and facetime are not possible now, whilst prices have been going up and up, they have tried various alternatives such as something which sounds like broadband via a microwave dish shared between residents of the area amongst other but these companies don't seem well run to put it politely and though speeds can be better, consistency and thus facetime is even worse,
I was wondering if any Spanish mobile company's offer a mifi box on 3g or 4g.. I've looked online but can't get a handle on things or if any coverage is available in the area..
So if anyone has any knowledge of such things over there it would be a great help ☺

Here's movistars one:

And Orange ES' one:

Stick the name of an operator and 'cobertura' into google

If it helps, Three have coverage maps showing the signal a roaming customer can receive in a foreign country. This might show you if there's some 3 or 4G in the place you're looking for.

Three's Spanish roaming partners are Telefonica and Xfera.

Thanks for that info, it's very helpful,..
Does anyone have a idea what network speeds on 3G and 4g are like across the networks in Spain? Are the speeds more like O2 & Vodaphone (eg: < 1mbps 3G & 10-15mbps 4g) or more like three and EE (10-20mbps 3G & 40+Mbps 4g)?

I think generally Movistar & Yoigo have the best 3G/4G footprint.

Yoigo is probably your best bet because it uses it's own masts as well as the ability to roam on Movistar's 2G & 3G network.
