I always thought of it the other way around: eSIM for primary, while using the secondary physical SIM slot for using local SIM cards while travelling.

Ideally either approach would work, it’d really depend on how mobile service providers around the world adopt eSIM.

In some countries it's very hard to get a local SIM card -- eg. in Germany a few years back (before EU limit on roaming fees) I struggled to get a prepaid SIM and activate it. You need to provide name and address to activate it, and they somehow check it, so they did not accept the address of the hotel...

I guess that would be easier with eSIM, because you could buy a plan that's targeted at travellers (instead of locals), and you wouldn't be limited to the SIM card selection they sell at the gas station.

The providers don't ask for that information because they want to, they do it because they have to by law. You'll have the exact same issue with eSIMs.

The carriers could still sell you a SIM and plan, but the administrative overhead for verifying the information of foreigners is probably deemed too large to still make these short term plans profitable by their metrics.

I don't see how it would be easier necessarily as I assume the rules in countries that make it hard to buy some cards as a visitor, would apply to companies selling esims too.

Many android phones offer dual SIM trays which shouldn't even preclude the ability to offer esim.

[jakobegger]

The regulations don't preclude selling SIM cards to people who live in a hotel. It's just that the incumbents don't care enough about travellers to make it easy because they are too small of a market.

With esim, the barrier to entry is lower -- a virtual mobile network operator could target travellers and make it easy to get a temporary SIM, without having to first build up a huge distribution network for physical SIM cards.

It would even make it possible to get a temporary SIM card from a different country, which would circumvent some of the restrictive regulations (eg. Germany requires registration with address for phones registered in Germany but allows you to use an "anonymous" phone registered in another country.)

This has been my experience - it's much easier to find a traveller-focused eSIM package - they just show up as options when you land somewhere.
