Hello,

is there any way to turn one, or multiple eSIMs into an rotating mobile proxy for a specific country?
Let's say I want to get sweden/turkey or german mobile proxies and have the possibility to put some setup in any cheap country, would I get one IP from the coutnry where setup is located, or one IP from the provider?

When I would make the IP rotating, I could live well off with just one eSIM with unlimited data. What is the catch?

It’s dont really think it is like that. The IP comes from the carrier, not your setup location, and eSIMs don’t just turn into proper rotating mobile proxies. That’s why people usually just go with providers instead.
 
The IP comes from the carrier, not the box location, but the bigger catch is reconnect control. One eSIM gives you one carrier pattern, not a real rotating pool.
 
If you use roaming eSIM then you'll get the IP from the carrier, not the location. Just make sure your data package support roaming on the location your server is.
 
It is a nice thing in theory, but in practice it varies a lot.

Main problems: unpredictable rotation IP pool size (down to too small for rotation-based work), unpredictable rotation rules (up to no rotation), hard throttling, hard pricing. You gotta check manually, no reliable way to look this up in advance.

In our own data, roaming-SIM setups like this are literally a few, I suspect that’s not by accident.
 
I'd also consider the carrier's fair-use policy. Unlimited data doesn't always mean unlimited proxy usage. Some operators start throttling or changing network behavior after sustained traffic, which can make the setup unreliable for long-term use.
 
Roaming eSIM can help with the country side, but it still does not give you a real rotating pool. You are still riding one carrier pattern until you add more lines or real reconnect control.

Best place to get an eSIM, please?
 
I believe you are asking about what the phone would do if you had one to many esims from different countries. I think you'd have more fundamental problems with a setup like that. Most phones only allow you to use one sim/esim for data at a time. If you were using a German esim in the US it would depend on how the owning company handles their traffic. T-Mobile for example routes all their traffic back through the US no matter where you are. YMMV for sure.
 
The main catch is that “unlimited” eSIM plans often have fair-use limits, throttling, or hotspot restrictions. Also, reconnecting doesn’t always guarantee a fresh IP because carriers use CGNAT and may keep you in the same pool.
 
Doesn't work the way you think it does. Roaming eSIMs route traffic back to the home carrier (showing roaming headers/flags), and a single eSIM won't give you a true rotating IP pool. Plus, "unlimited" mobile data plans kill your speeds under FUP as soon as you run heavy traffic. You're better off running cheap Android phones/dongles directly in the target country with local SIM cards.
 
You'd get the IP of the carrier, doesn't matter where the box with the sim is. But careful with travel eSIMs, many of them send traffic through the provider's gateway, so you buy a Swedish one and ipinfo shows you Netherlands or Singapore. Test that first. And one sim gives you one IP at a time, so for multiple sessions at once it's not enough. Unlimited plans also have fair use, after some GB they slow you down. At DataImpulse we also run a mobile pool.
 
You'll usually get an IP from the SIM's home carrier, not from where the hardware sits, because roaming data is normally routed back home. A German SIM in a modem in Portugal still exits with a German IP. Travel eSIMs are the exception, since they often route through a hub in another country, so test before building anything. The catches with one unlimited eSIM: EU carriers can cut off SIMs that are permanently roaming, most consumer plans ban tethering and commercial use, and one SIM can only rotate by reconnecting, which drops every active session.
 
the ip doesnt always match where the device is located. with roaming esim the traffic may exit through the home carrier, roaming partner or some central gateway, so you need to test the actual plan. if you need a real german ip for example, safest way is a german sim with the modem actually connected to a german mobile network

the catch with one unlimited esim is fair use, throttling and carrier terms. many unlimited plans dont allow this usage, especially while roaming. also reconnecting mobile data doesnt guarantee a new ip, sometimes you get the same one again. most carriers use CGNAT too, so you normally need your own server or tunnel to access the proxy from outside
