I'm on Verizon postpaid, 4 lines on Unlimited Plus for $31/line. That's hard to beat pre-paid for comparable service. Yes, I have to threaten to leave Verizon once a year to get them to add a bunch of customer loyalty discounts, but that's not less work than switching pre-paid carriers to chase deals.

I subscribe to /r/NoContract/ so I have a pretty good idea what's out there.

Visible+ is a comparable pre-paid plan, it's $29/mo but that's a teaser rate and to keep it past one year, you'd have to port out and port back in for whatever deal they have in one year. The normal price is $35/mo, so I'm beating that. (Visible would also mean managing 4 separate accounts since they have no multi-line plans.)

Total Wireless is a bit cheaper ($26/mo) but I keep reading terrifying customer service issues with them including most recently losing number during the porting process.

Aside, I briefly used US Mobile earlier this year to port a VoIP line to Google Voice (GV will only port-in mobile numbers). US Mobile's customer service is exceptional. Would recommend them heartily for pre-paid service. But they don't currently beat what I'm getting from Verizon post-paid. I'd consider them if I can't keep my loyalty discounts next year.

It should be noted that with Visible+ after the $29/mo promotional rate ends in 12 months and it goes to the regular $35/mo you could switch to the annual plan. That's $375/year, equivalent to $31.25/mo if we ignore the time value of money.

Another thing to note about Visible+ is that if you have an Apple Watch with cellular and want to use that with your plan there is absolutely no reason to consider Visible+.

Watch support can be added for $10/mo but that brings the total to the same as their highest level plan, Visible+ Pro, which includes watch support. That plan is $45/mo $450/year ($37.50/mo) and promotional discounts run out.

As far as I was able to tell, Visible+ Pro is the best or very close to the best deal for people who want Apple Watch support in the US and only want one line. You can get lower prices per line on postpaid plans with multiple lines but if you will only have one the postpaid plans are ridiculous (even before you add in watch support).

Metro By T-Mobile works well, if you navigate through the website to find the $25/month ($30 without autopay or for the first month) postpaid unlimited plan. It is a T-Moblie MVNO.

It is hard to get eSIM to work, but they have good customer service (but you need accses to a phone to call them, so you should try something like textnow or Google Voice) which helped my friend set it up.

It is not a intruductory offers, AFIK.

My internet provider (Spectrum) is a Verizon MVNO and is cheaper than that. I’ve got two lines and a watch add on for $70/mo, and I don’t even have their internet service anymore because I switched to a better fiber to the door provider.

I check with people that come around or in random stores if they can beat it, alas they cannot.

Visible has a family/friends plan - called "Inner Circle" - that comes with a $5/month discount on the Visible+ or Pro plans, and allows one account to pay for all the others.
