Regarding the Expense of eSims... there is no arguing, in general travel eSims are more expensive than local options. That said... you are paying for convenience. Not having to worry if that airport kiosk is open, not having to worry about a language barrier, or currency etc... just turn your phone on when you land.I've just came from Thailand and Japan, local SIMs are cheaper (or a little more expensive but in return way more data).
And definitely in the UK you'll get better for your money with a British SIM on a smaller network.
Another thing I discovered. If you ran out of data on your eSIM abroad, you're completely dead until you find free WiFi. And even then, some countries block eSIM services like Airalo to top up, so you are effing screwed. Especially in China. Thank God I had a VPN to bypass and top up. That's one country you're better off with a local SIM.
Anyway, I like eSIM but I want SIM tray as backup. Thank God I live in a country (UK) that I can have the best of both worlds.
In Japan specifically, I used Holafly (to test it out) on my son's phone back in July. It have him "unlimited" high speed data for the week we were there, and was like $27. Yes, that IS expensive.... but my time on my vacation is worth something to me as well. Not having to futz with finding a local sim, made it worth the upcharge for me.
As for China...we were there before Japan. I disagree with a local sim being better in China because:
- Censorship - Most western apps from Gmail through Whatsapp and discord that my son uses simply don't work on Chinese Sims or Chinese wifi. A travel eSim bypassed the great firewall of china without the need a VPN.
- Running out of Data - Seems like a combination of poor planning and or poor vendor UI. You should be sure to top off your data BEFORE it runs out, especially if it is mission critical for you. Also, not a bad idea to have a backup eSim. I like Roamless as their business model is you pay a price up front to bank in your account. Usage is pay as you go and it never expires. Roamless is expensive in China, but in a pinch you could turn on the roamless sim long enough to top off your other provider. If data is mission critical, definitely don't rely on just one provider.
- VPN - This is a must have for China IMO. Nord and Express didn't work for me while I was there. I was able to use my Google FI data connection to download Mullvad which works brilliantly there.
- eSim tray as a backup - I agree with you in theory. My last phone with a physical sim tray was iPhone 12 Pro Max. That phone could only have one eSim active at a time. Which meant that If I wanted imessage etc to continue working while I used an eSim, I needed my primary US provider to be on a physical sim. Conversely, if I has my US provider on an eSim, then I needed to find a physical sim everywhere I went... so travel esim provders were off the table. For me the best of both worlds would be the ability to have two eSims active AND a pSim slot to use in a pinch. Dunno if iPhone 13 supported that or not. Anyone know which Android phones can do that?
- My General preference is to have good native roaming. Google FI has been amazing for this over the years. I had 50GB of high speed data to use pretty much world-wide. No messing with local or even travel eSims needed. Only native roaming that comes close in convenience and price is AT&T's Business Elite lines which come with 7 free travel passes per month per line.... which give you unlimited high-speed data for 7 days free, then charge an outrageous $10/day.
- My Current setup (post summer travel) is Visible+. While it does have the option for 1 free day pass and then $10/day.... that option is stupid. Instead I'll just pair it with one of the zillions of travel eSim providers out there. Plus I'll still have my Roamless eSim as well as the Visible native option in my back pocket if things go sideways with my esim provider... planning ahead for contingency for the win.
