I'd be very curious to see what would happen if you temporarily swap SIMs. Would the tethering ability stay with the device or the SIM?

I have swapped sims recently in an iphone 6 while in NZ. The sims were a US T mobile data only and a Fi data sim. I know the T mo data sim did allow a hotspot on the iphone 6 at the 2G capped rates, showing a LTE or H antenna connection. It also allowed a connection when I put in a data only Fi sim, but I used the phone for surfing and maps, didn't try the hotspot because I could do that without a problem on a Moto X4, that I also had with me.

I think T-mobile just sent those out regardless of how much data (or how fast) you use oversea. I switched my family to T-mobile in December last year. I switched myself to Fi. So we went to Europe for 2 weeks late Dec and early Jan. I used like 4.5 GB on my Fi while my wife and kid used about 1.0GB combined. In Feb, both my wife and kid got the "threatening" txt saying that you can't roam blah blah blah.... and that was roaming on the One Plus speed of 256KB/s max. My Fi never complained and I got 100+ MB/s speed in Paris.

Yep. In my past use of FI I never had any issues. I just don't feel like paying twice as much w/ T-Mo's Unlimited speed plan only to have to deal with this kind of foolishness.

It seems like more and more lately, I'm having problems with my Fi data connection on my Pixel 3. This is here in my hometown, not international or even traveling domestically. I'll have 3-4 bars, and an LTE connection, but either get no data at all or extremely slow speeds.

The problem is intermittent, sometimes it works fine and other times, not. Calls & texts still work. And data works perfectly on wifi.

I've tried the suggestions I've found googling the issue, to no avail.
- reboot the phone
- toggle airplane mode on and then off
- clear the Fi app data cache

Has anyone here had similar issues? Ideas to resolve?

Sounds like whichever network you're on is having issues, either something broken or too much load. You can download Signal Spy and see whether you're on T-Mo, Sprint or USCC, and you can use it to force the phone over to a different carrier as well. Note that if you're in the 85% of the country where USCC doesn't exist, forcing USCC will usually get you a Verizon EVDO connection, which you should expect to be really slow.

Yeah I use a paid app called FiSwitch to do the same. The Fi app doesn't do a good job of switching network. It seems to prefer Sprint network and over here Sprint is the worst carrier. Usually I have to force it to go T-mobile. At work, I don't get Sprint nor T-mobile. I have to force it to USCC, but I don't think I am on USCC.. not sure who is the actual carrier, but I get full signal 3G which is good enough for me. Well better the 0 signal LTE from Sprint or T-mobile LOL.

I actually like using FI on my iPhone specifically because it does NOT switch to sprint.

There is a 1/2 price sale on the Pixel 3's. Requires activation. April 22 only.

Damn, I thought I had a bit more time to sell my Pixel 3 xL before they started dumping them on the market as the Pixel 3A & 4 come closer to launch.

Got a Pixel 3 XL 128 gb not pink. thats all they had left by 1 pm CST. Oh well. Trade in Moto X4 only gave me $39, but I feel better about the environment. I hope the camera is as good as they say, got some serious photo opportunities coming up.

I use both Fi Switch and Signal Spy, and I have the actual dialer codes for copy/paste to force a switch in a Keep note. Had some trouble in Copenhagen a couple of years ago, and the tech suggested I keep the codes handy. It was not a problem last month anywhere in NZ or Fiji.

I didn't try the switch code oversea since t-mobile was working just fine. But I thought you cannot switch anyway when roaming aboard? Could you switch from T-mobile to Sprint's roaming partners? I thought you could only use T-mobile internationally?

Pixel 3 night sight pics are amazing. Most newer phones could take good day time pics, so really low light pics are the most important ones. Here is a pic I took inside Notre Dame back in January before the fire. It was really dark inside.
