Quick answer
What is the best US mobile proxy: T-Mobile, Verizon or AT&T?
Pick the carrier your users are on; if you have no preference, T-Mobile is the usual choice for speed and Verizon for coverage, according to Ookla's first-half 2026 report. CellMast rents dedicated US mobile proxies on all three: a 4G/5G modem with unlimited data and a new IP by link, API or timer, for $3.75 per day or $45 per 30 days. No KYC — no ID, no selfie, no documents. Pay in crypto.

"—" means we found no comparable sourced figure, not a weakness. Subscriber totals for T-Mobile and AT&T are not shown: T-Mobile stopped reporting total subscribers in 2026 and public lists disagree.
Which US carrier should I choose for my mobile proxy?
- Testing an app or an ad for a carrier's customers: choose that carrier. Prepaid brands use their parent's network: Metro and Mint on T-Mobile, Cricket on AT&T, Visible on Verizon.
- Speed and 5G: T-Mobile, which won fastest 5G in Ookla's first-half 2026 report.
- Coverage outside cities: Verizon, which won best coverage in the same report.
- Several client brands: one port per client brand, on the carrier and in the city that brand's users have.
- No preference: take whichever carrier the checkout lists in stock.
How common is IPv6 on US mobile networks?
On AT&T Mobility's network (AS20057), APNIC Labs measured about 87% of users as IPv6-capable in October 2026.
Where a network still gives IPv4 addresses, subscribers share them through carrier-grade NAT; see the CGNAT guide. Whether a port also gets an IPv6 address depends on the carrier and the modem; check it with an IPv6 test page.
How much does a US mobile proxy cost?
A dedicated US port costs $3.75 for one day, $15 for seven days and $45 for 30 days, as of October 2026, on any of the three carriers, with unlimited data. Canadian ports on Rogers, Bell and TELUS are in the same zone at the same price. The price index compares these prices with other providers, with dated sources.

How do I check which US carrier my port uses?
The client area shows the carrier of each port. You can also check from outside: send a request through the port and look up the address. T-Mobile addresses belong to AS21928, AT&T's to AS20057 and Verizon's to AS22394 or AS6167.
curl -x http://PORT_USER:[email protected]:7777 https://api.ipify.org
# look the IP up (e.g. https://ipinfo.io/<IP>): AS21928 = T-Mobile, AS20057 = AT&T, AS22394/AS6167 = VerizonDo US mobile IPs geolocate to the right city?
Roughly. IP databases place carrier addresses near the carrier's internet gateway, which is often a large metro area, not the modem's town. For city-level checks, compare the result in two IP databases and ask support whether a port is in stock in the metro area you need.

A dedicated US port costs $45 for 30 days at CellMast, as of October 2026, on T-Mobile, AT&T or Verizon, with unlimited data, and rotation by link, API or timer. A one-day rental costs $3.75.

Can I switch a US port from T-Mobile to Verizon?
Yes, on request to support, if a Verizon port is in stock. The port moves to the new modem and keeps the time left on the rental; credentials may change.
Do I need a US address or ID to buy?
No. CellMast asks for no ID, no selfie, no documents and no address. Login with an account number; email is optional. You pay in BTC, USDT, USDC, ETH, SOL, LTC from a $25 top-up.
What is a US mobile proxy used for?
Testing US apps and checkout flows on real carrier networks, checking which mobile ads US users see, tracking US mobile search results, and running the official accounts of US brands from a stable carrier IP. Fraud, spam and credential attacks are banned by the Acceptable Use Policy.
