Will there ever be a consumer offering along these lines? (i.e. i am travelling around and don't want to have to get travel SIMs in every different country I visit).
We won't build specifically for consumers, we're targeting customers with 1000+ devices. My plan is to move my T-Mobile consumer subscription to my eSIM on my iPhone X once T-Mobile supports it and then put a Super SIM in my second slot for global data.
Google Fi is great for this. Wherever I land abroad I'm connected within a minute and pay the same data rate that I do while at home.
What phone do you use for this or is it multiple phones, and what SIM or is it multiple SIMs?
With Google Fi you have to have a Google Pixel Phone, and it just works. Google is a MVNO so they can buy tower time from any carrier.
Edit: And yeah it's a single SIM.
Unfortunately it's only available to US customers.
This exists, but pricing can be exorbitant and availability is heavily location dependent.
Amazon kindle used to do this back in the day. Then people started tethering them and then all the kindle 3's and before got limited to 50 mb/month. (Later ones just had no internet outside amazon/wikipedia iirc)
Unlimited 3G everywhere was why I bought mine. Never tethered it either, but it was limited just the same :/
