Joe, have you used this recently? It's been my current experience (in the last 2-3 weeks) that Google won't let you verify through VOIP anymore. It seems to have to be real sim cards.Twilio. We use it for each and every new google account. Gmail and GMB.
Do you mind explaining this more? If I'm understanding you correctly, you can refresh the IP of your mobile hotspot? Any directions?An alternative work around is to have a mobile hotspot available the IPv6 and refresh the IP address once you hit a limit. It works, but it will add cost to the operation. The best thing to push is to have a client provide an email address for you to use.
My phone I use for business already has a hotspot so I'd love to just piggy back off of that (unless we're talking about something different here). I wonder how I can reset the IP when I hit my gmail limit? Or does it reset each time I connect to the hotspot?I think it depends on which one you buy. I can't remember off hand which one we used when I was still working agency (that was about 6 months ago), but we had a hotspot that we rebooted each time we needed a new email address which created a different IP address we could connect to. It worked well and saved a lot of time, since twillio numbers were hit or miss because of the situation I mentioned above.
Editing this to show one example (possibly affordable solution):
Mobile Broadband Unlimited Data Plans w/ No Annual Contract | T-Mobile
Most hotspots don't provide static IP's, so it really comes down to cost. T-Mobile is typically cheaper than the bigger guys (Verizon, Sprint), so it might be a viable option for you
