I'm hoping for a more global solution. (T Mobile coverage in Canada is "less than stellar".
I have a T M data sim in my iPad. The best part about the TM sim is that they don't let you quit. I stopped paying the monthly over a year ago and each month since then I have been "gifted" another 200 mg which is enough to pick up my email from time to time. I guess they like to pad their stats.

I found "interesting" that Orange France charges the user for SMS they sent themselve and that they cost even more when out of the country. I am extremely surprised though that the dude couldn't be served in English at all.

You can buy an Estonian prepaid SIM (at any gas station or supermarket info desk, no registration or ID needed) and it will roam in the EU and elsewhere. Just need to put some money on it.

This one is 4G and runs on the Telia network, best one in the country and around Scandinavia. Others are available, and prices are very cheap.

In terms of EU limiting the roaming costs, yes, they are very cheap this year and will become free (i.e. domestic pricing all around the EU) from June of 2017.

After 15 June 2017 the costs of using a phone/data in any EU country are the same, as long as you have an EU SIM.

Mobile roaming costs - Your Europe

Brits please note, tough luck after Brexit, suckers.

If you need a phone as well and you are American or have access to the US to set up and activate an account there, check out Google Fi Project.

Google has purchased blocks of time and data in 143+ countries and repackaged it into their own mobile offering. It's great! We used it in 32 countries around Europe, South Africa, Mexico and Canada (and the US, of course).

The coverage is the best possible since it does not rely on just one provider per country but automatically switches the local carrier with the strongest signal in your current location.. The price is way cheaper than buying SIM cards everywhere, it's a million times less hassle, since the switchover between countries (and continents) is seamless, and its reliable.

At $10US per gig of data and for only what you use, not a guessitimate program, it's often easier and the signal stronger than many hotel rooms offer and cheap enough to use data because you want to not only because you need it like blood! Airports that subject you to slow sowed should, advertising and short connections, we don't bother with them anymore.

I know this sounds like an advertisement for this but it isn't. I'm just impressed when once in a while you get a great product and a great price, that actually works as advertised.

It answered all our needs at a great price. I've even given up my cellphone account in Canada. It's cheaper to use the US Google Fi network even roaming! (Canada has terribly expensive cellphone costs.)

I detested Google Project Fi when it foirst came out and even for many months after that when it was no longer a beta offering because it let me down very badly in South America, Canada and even back in Australia. However in the last six months they have finally got their act together and it is much more reliable. Not perfect by a long shot, but certainly fairly reliable. I'll be interested to see what it is like when I head back down to S America in a few months. Central Europe through to Denmark and then on the ferry to Iceland, it worked perfectly although once in Iceland I got a great deal on a local SIM and so suspended the Fi service while we were there (which is another advantage of FI - suspend and reinstate on a daily basis if you want to.
The cost of $10/GB worldwide for data and Skype-type call costs all over the world is a pretty good deal. Recently I tried to get a better deal here in the US (where calls are free) but once you started wanting to use the phone as a hot spot, all the great US deals evaporated and all that was left was similar in cost to the fI.

Catch, and there always is one, is the android phones required for the service are at the high end regarding purchase price,

BTW Not sure whether Steve has used his service outside North America, but it is NOT always perfect. There is a huge thread on the topic on Google Forums and there are still plenty of negative reports, although far less than before. Just don't rely on it to call and ambulance if you need one urgently

I've been using it now for almost a year and it has been excellent...flawless...from Sweden to South Africa and Canada to Mexico. Gold standard I'd say. I didn't have one when I did South America, but I wish I had! Good luck in your travels.

I use a UK '3' package (Feel at Home) which costs £10/month and gives me my UK allowances (calls/SMS/data) in most EU countries and many others (42 countries currently). I get 1 GB data, calls, SMS inclusive.
