“I recently moved to the US from the UK and my wife and I want to switch from her $150/month AT&T plan. We don't use much data and are looking at MVNOs like Mint, Visible, or US Mobile. What is the best value mobile provider in Massachusetts/New England for reliable coverage without needing home internet bundles, and what is the catch with these cheaper MVNOs regarding deprioritization or speeds?”
You do not need a home-internet bundle or another $150 plan to get dependable service. The manageable part is that you can test coverage before moving either number and keep the two lines on different underlying networks if that works better.
You have three sensible stand-alone mobile routes, but US Mobile gives your low-data household the best balance of price and network flexibility.
Best overall value: 5GB of shared data with unlimited calls and texts starts at $15; the first line is included and the second is $8, making $23 per month for both, with taxes and fees included. Data can be shared across lines on different US Mobile networks. Start with Warp on a 5G phone where Verizon-style reach matters; if your present AT&T signal is proven better, Dark Star is the AT&T-based option. Warp is labeled as on 5G devices, reducing the usual congestion catch.
Good if T-Mobile coverage is clearly best at your places and annual prepayment is acceptable: two 6GB plans cost $360 upfront for 12 months, equivalent to $30 per month combined, plus taxes and fees. The catches are lower priority during congestion and possible 128 Kbps service or suspension after each line uses 6GB that month.
Good if you want unlimited data rather than the lowest bill: two stand-alone lines cost $50 per month total, taxes and fees included, on Verizon's network. During heavy traffic data may be temporarily slowed; hotspot data is unlimited but capped at 5 Mbps, and support is online chat rather than stores or telephone.
New England is not one coverage market: use the newer FCC-based rankings only as a starting point, then test before moving your numbers.
These steps let you test coverage first, unlock the phones and then move both numbers without cancelling AT&T too early.
Before buying a plan
Confirm that 5GB shared is enough
Add the two lines' data use for each of the last three billing months. If the combined figure consistently stays at or below 5GB, use US Mobile By the Gig at $15 for the included first line plus $8 for the second—$23 monthly, taxes and fees included; if it does not, Visible base is the researched unlimited fallback at $50 total for two lines.
Requirements
Before porting either number
Run Visible's free coverage trial
Open https://www.visible.com/free-trial/ and install the 15-day trial eSIM. It requires no card, gives you a temporary Visible number and leaves AT&T active; use it at home, work and on your regular Massachusetts/New England routes. This tests Verizon coverage, although actual congestion priority can differ from US Mobile Warp.
Requirements
Before activating another carrier
Unlock both AT&T-bought phones
Submit each eligible device at https://www.att.com/deviceunlock/. AT&T says approval usually takes a few minutes but can take up to 48 hours; do not request the transfer PIN until the phones are ready.
Requirements
After the coverage test
Activate US Mobile By the Gig
At https://www.usmobile.com/plans choose By the Gig with 5GB shared data, add the second line and confirm the displayed total of $23. Choose Warp first on a 5G phone if the Verizon trial was strong; choose Dark Star where your present AT&T service is demonstrably better. US Mobile permits shared data across lines on different networks.
Requirements
Within 4 days of getting the PIN
Port the numbers before cancelling AT&T
In the AT&T account, go to Profile → Settings → Transfer phone number → Request new PIN, or call *PORT and follow the prompts. Give the PIN—not the AT&T account passcode—to US Mobile when starting each transfer. Keep AT&T active until both ports finish; the FCC says simple ports generally process in one business day.

Mint Mobile Network Management Policy
Mint distinguishes temporary congestion deprioritization from the much slower post-allowance treatment on fixed-data plans.
Customers may notice reduced speeds in comparison to customers with a higher priority during network congestion. Each of our current, non-Unlimited data plans (e.g., our 6GB, 17GB, and 23GB Plans) features a designated allotment of high-speed data, after which your data speed may be reduced to 2G speeds (for most plans 128 Kbps) or your data access may be suspended for the remainder of the applicable monthly period, as described in Section 9.6 of the T&Cs (‘Data Usage Level’).
Visible base plan
Visible's own plan disclosure establishes its regular price, host network and congestion treatment.
Unlimited data, powered by Verizon, for $25/mo taxes and fees included. When the network is experiencing heavy traffic, your data may be temporarily slowed. Visible includes mobile hotspot with unlimited data at speeds up to 5Mbps.
Visible Free Trial
Visible provides a no-payment way to test Verizon coverage without disturbing the current number.

Navi Massachusetts FCC-based coverage guide
This current FCC-based guide ranks the underlying networks while warning that modeled coverage is not a personal guarantee.
Verizon delivers the most 4G coverage in Massachusetts, covering 85% of the state with its network. The FCC incorporates standardized propagation model assumptions into its data, and notes that a user’s actual experience may vary based on end-use factors like network congestion and terrain.
FCC Number Porting Consumer Guide
The FCC establishes the correct sequence for keeping a number while switching.
Do not terminate your service with your existing company before initiating new service with another company. Contact the new company to start the process of porting your number.
AT&T Device Unlock Policy
AT&T's own policy states the main requirements for unlocking an AT&T-bought phone.
Device bought 60+ days ago: You purchased your AT&T Wireless SM device more than 60 days ago. It isn’t active on another AT&T account. Device paid in full: You paid for your device in full at purchase or paid it off through an installment plan. Your installment balance must be zero before unlocking.
AT&T Number Transfer PIN
AT&T establishes the personal-account transfer-PIN deadline and warns against disconnecting first.
Your Number Transfer PIN will expire 4 days (14 days for business accounts) after you request it. Don’t disconnect your AT&T service before asking a new service provider to transfer your number.
