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](https://cellmast.com/guides/cgnat-mobile-ips/). 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](https://cellmast.com/data/mobile-proxy-price-index-2026/) compares these prices with other providers, with dated sources. ### US & Canada port plans | Plan | Quantity | Price | Price per unit | | --- | --- | --- | --- | | US & Canada · 1 day | 1 port · 1 day | $3.75 | $3.75/day | | US & Canada · 7 days | 1 port · 7 days | $15 | $2.14/day | | US & Canada · 30 days | 1 port · 30 days | $45 | $1.50/day | In every plan: One modem and SIM reserved for you · Unlimited data (fair use, no resale) · New IP by link, API or timer · HTTP, HTTPS and SOCKS5 Prices in USD per port, as of October 2026. **Before you pay** - Minimum top-up $25.

Typical network confirmation time: BTC ≈ 20 min · USDT TRC-20 ≈ 1 min · USDT ERC-20 ≈ 5 min · USDC ERC-20 ≈ 5 min · ETH ≈ 5 min · SOL ≈ 1 min · LTC ≈ 15 min ## 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. *See the carrier IP of a US port* ```bash curl -x http://PORT_USER:PORT_PASS@gw.cellmast.com:7777 https://api.ipify.org # look the IP up (e.g. https://ipinfo.io/): AS21928 = T-Mobile, AS20057 = AT&T, AS22394/AS6167 = Verizon ``` ## Do 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. ## US carrier pages - [AT&T](https://cellmast.com/mobile-proxies/united-states/att/) — United States - [T-Mobile](https://cellmast.com/mobile-proxies/united-states/t-mobile/) — United States - [Verizon](https://cellmast.com/mobile-proxies/united-states/verizon/) — United States ## US mobile proxy: questions ### How much is a US mobile proxy per month?
