Very happy with my SIM-only PlusNet subscription in the U.K. Good price for 20 Gb / m. Good access to 4G in most of Britain. However their 2022 Roam-Like-Home promise has left me completely underwhelmed in the EU this year. In the past few weeks travelling through France, Germany, Austria, Hungary and Croatia, PlusNet has only enabled access to a maximum of 3G, sometimes only 2G (E) or worse. It has never been good enough for a Zoom call in any of these countries.
However I have needed better connectivity than this and I have found good 4G almost everywhere using a Netgear mifi with a (French) Free 5G pay-as-you-go SIM card. It costs 29.99 Euros for the first month, then 19.99 per subsequent month. That gives 210GB per month in France and, importantly, 25GB per month in other countries in the EU and several elsewhere. For the last few weeks it has worked flawlessly for me. Even when I went over the 25GB outside-France allowance it cost only 3 Euros per extra GB, unlike the punative rates charged by some U.K. carriers. If I had had a 5G capable mifi the internet speed would have been even better. “Free” reputedly has better 5G coverage in France than any of the competitors.
At present, “Free” SIM cards are only available through their high street “boutiques” in France and in outlets such as some supermarkets, but it seems a better deal than most and despite my limited French the shop assistant was very helpful.
