eSim for Multi-Country trip

Can't help with ESIM but TMobile is flawless in tgese and cheap under most circumstances.

I have used Airalo in all those countries ( but I have also used it in Spain 2 or 3 times without a problem). I usually buy the regional eSIM for Europe when I am going to more than one country.

I've decided to use Bcengi this year since--like you--I'm going to quite a few different countries. Bcengi's eSIM works in most countries and is usually less expensive, per GB, than Airalo. Rates do vary by country, so it's important to check the price list before committing. I scanned the entire worldwide list, and I remember seeing a few places that seemed painfully expensive.

In addition to the (probable) lower cost per GB of data, Bcengi has the advantage of providing portable data. When you cross a border, you just keep using the same eSIM. You don't have to guess how much data you will use in each country and then, if you've underestimated, buy another one-week eSIM to get through your last day or two. You add more money to your Bcengi account as necessary.

I'm using the Bcengi eSIM at home in Washington DC, where it is doing very well. That's obviously not the same thing as bouncing around Europe. I've been happy with Airalo's coverage in the past, but it has not been perfect. Nor was Google Fi on the occasions when Airalo seemed to be choking and I briefly switched back to Fi. Honestly, I think sometimes the problem is the local carrier with whom the eSIM company has contracted. And there are places like the narrow alleys in Venice with 4- story buildings on both sides that seem to present physical challenges.

I usually use Nomad and it has worked well for me. They have single country and regional plans. Check the Europe plans and see if an option includes all your countries. One esim that picks up the local cellular network of each country. If you click on the country and details, you can see which carrier Nomad partners with in that respective country. Sometimes it's just one or a couple.

If you download the app on phone and buy thru there, the activation is pretty straight forward. I know you can top it off if you are running low on data, but I am not sure if that extends the esim beyond the time limit at original purchase. I need to read on that but I usually don't travel for more than 2 weeks so I buy one with 30 days.

I will buy the Europe plan later this year.

I will check out Nomad and Bicengi. But the note about sometimes the problem just being the local carrier has value.

I am currently traveling with 2 friends: me on my home ATT cell data, one friend on the same, and one using an Airalo plan. Last night when we came out of the Globe in London, neither me nor the friend with Airalo had any coverage. The third friend using the same method as me did. I was able to turn my phone off, then back on, and have coverage - but it was odd.

And we have problems here in the city canyons and in the ancient buildings with 4 foot thick walls.

In Texas my television service was 5G, when I asked about that here, I didn't think the laughter would stop.

I am making the same trip to the same countries, plus Slovakia, in May and I plan to use Roamless for the first time. Roamless is pay-as-you-go. In roamless, a person deposits money to purchase "flex credits". The flex credits never expire until you actually use them.

For Europe, Roamless charges $2.45 per GB. I usually use about 5-10 GB for a 3 week trip. Based upon my usage, this should work out much cheaper for me than buying a fixed amount of data which usually expires (wasted) after 30 days.

Another benefit of Roamless is that I can make in-app telephone calls to anywhere in the world. Being able to make a phone call within Europe $0.04/minute (e.g. calling hotel or restaurants etc.) or back home to Canada $0.06/minute (e.g. family, friends, bank etc.) is very valuable to me. I can even "verify" my cell phone number in Roamless for free so that when I make the call, it appears to come from my cell phone number. Very few travel esims have a telephone calling feature. One exception is Orange Holiday.

Please note that people phoning to my cell phone number will not work in Roamless. My workaround is to set up a free TextNow number and to call forward my cell phone number to TextNow which can take calls anywhere in the world.

Also, please note that you cannot text to or from Roamless (e.g. no 2FA) unless you pay extra and subscribe for one of Roamless telephone numbers. But this is always a limitation for any travel esim.

Bcengi and Jetogo are similar pay as you go Esims and are cheaper than Roamless. However, neither Bcengi nor Jetogo have the ability to make phone calls like Roamless. Also, I have read and I can tell that the Roamless app is excellent and works very well.

Roamless has a promotion where you could get 3 buckets of 3GB data each for 3 groups of 25 countries each for free. Those three buckets cover the five countries that I will be visiting in May and are valid for 6 months. I expect that I may not have to pay anything for my trip. The promotion codes were ROAM25, ROAM50 and ROAM75. Hopefully, those codes are still valid for you.

In addition, if you use a referral code, you can get an additional $5 of flex credit when you sign up and make your first purchase of $5 flex credit. If you need a referral code, please feel free to private message me.

I cannot personally vouch for roamless, until after my May trip. However, I have read a lot of positive reviews in Reddit and I have a lot of confidence that it will work out for me. YMMV.

Good luck.
