Well I was a little disappointed the Pixel 3 won't likely get true DSDS or DSDA because it doesnt have two IMEI numbers. Apparently a beta Q did have it in there, then the next beta update took it out. I think you can put it back with root, and I have a refurb 3 XL coming so I will look at that next week. So today I played around with the Pixel 3 XL (not the Pixel 3a, which does have DSDS) I put a MVNO that i have purely for the domestic data and as a throw away phone number which is priced at about $1.7 a GB, and a lot in the monthly GB bucket. (not providing name since they might lock it down). Both the MVNO sim and a T Mo data sim booted immediately and provided enough data here in rural texas to get by. I can live with that at this point and just switch manually, which takes 5 seconds, and another 15 to get registered on the network. The best part is that neither sim is blocked as a hotspot, so that is a win. Plan to use the MVNO for domestic data while traveling, and the T Mo data sim for international trips. Calls and especially texts are forwarded to the work phone for 2 FA stuff.
