For travel, it’s great. When I went to Germany four years ago, getting data on my phone without paying an exorbitant roaming fee involved waiting until I got to Germany, buying a SIM card at a train station, then finding WiFi access so I could complete the registration process, which involved a video call with a Deutsche Post agent to verify my passport for some reason. The last time I went a few months ago, I bought an eSIM before I left, and it activated automatically as soon as I landed in Europe.
Granted, I think a large factor in the hassle the previous time was due to German regulations involved in getting a phone number, but since I didn’t want or need a German phone number it was just unnecessary hoops to jump through. Now I can buy an eSIM from any number of countries that is valid throughout the EU with way less hassle, and I can get service from whatever provider I like rather than having to depend on whichever SIM card I happen to find at the local shop.
I’ve also never had an eSIM swap take hours to days—they’ve always been effectively instant for me. When my phone was damaged and I couldn’t get the eSIM transferred to a temporary phone while I got it repaired, I was surprised by how easy it was to generate a new eSIM online. If I had lost my phone, and I had a spare phone to use, getting service transferred with an eSIM would be a matter of minutes, rather than hours or days to get a replacement physical SIM.
Last time I went to Germany (2015), T-Mobile had run out of physical SIM cards. We queued up at Vodafone for half an hour. By this point, the store was closing. The employee gave us a SIM but didn't activate the plan correctly. So our €10 was all used up with hours instead of being good for a month. And we had to go back in the next day to sort out it.
eSIMs, EU roaming regulations, and carriers like Google Fi have all improved the situation markedly. Though dealing with Vodafone has not.
