Multiple Country Sim Card

What is the first country that you visit and what are the other countries on your itinerary. Generally, the one sim will work all over the EU. Sometimes the number of minutes or data is reduced when you leave the home country. Just need to read the terms and conditions for the particular sim.

Thanks! If we are just looking at EU countries is there a good suggestion on SIM card companies that you think are better than others?

Many UK companies have changed T&Cs this year to charge again for European roaming (This is post Brexit), but my understanding - and I am open to correction on this, this that most EU Sims will work equally in any other EU country (Because part of the premise of the EU included free movement of services).

As suggested, I'd research SIMS in the first country you intend to visit to get the best deal for you, and just use this.

It needn’t be overthought. Just buy a SIM from a large carrier in the first country you arrive to.

Orange bought in Spain worked in a number of EU countries - until it expired after 28 days. Cards bought in Serbia, Albania, Croatia and Slovenia don't work outside the country you bought them in.

You can buy the Orange Holiday card ahead of time from Amazon. I have used one 6 times, and my daughter has used one 5 times, and no problems anywhere in Europe, including Iceland and microstates. It gives you text, calls and data, and you'll know your Europe phone number ahead of time. It might be 10 bucks more than buying the same in Europe but it's nice to have you phone up and running before you get off the plane. I put my Orange SIM in as soon as wheels are down.

Every year I forget the registration process (not necessary for card to work; necessary if you want to add minutes/data after the two week expiration). But you just register it online before you leave home with your pertinent info and it's good for as long as you recharge it.

I also plan to buy an Orange eSim for our upcoming November trip to Spain. You can buy directly from Orange by using the following link or download their app from the Apple App store or Google Play store. It is cheaper than buying from Amazon. I emailed Orange and they responded that I can purchase the eSIM and load it in my phone while still in North America. A telephone number will be assigned so I will be able to provide that number to hotels etc even before I leave Canada. Once I land anywhere in Europe and use the phone for the very first time, it will activate.

Usually I prefer to buy my SIM after I arrive so that I can deal with a dealer in case there are any activation issues. But I'm going to test out the convenience of using orange this time.

When I bought a SIM card, I once had problems. The customer service phone rep. didn't speak a word of English.

We just sign up for international service on T-Mobile for one month, and we then cancel the service upon our return home.

T-Mobile is owned by the German telephone company and the cell phones there work exactly as it does at home. We once kept getting phone calls from a 3 year old granddaughter when we were in Budapest. She didn't know it was 3:00 a.m. in other places.
