πŸ’‘ Tip

How We Ranked These

We evaluated carriers based on five weighted criteria specific to San Jose's geography and demographics. Coverage reliability (30%) was measured using FCC-mandated coverage maps and crowd-sourced data from OpenSignal and RootMetrics for 2026-2027. 5G speed (25%) came from median download speeds in San Jose's urban core and suburbs. Price (20%) considered single-line unlimited plans and family plan costs. Customer service (15%) used J.D. Power 2026 California Wireless Satisfaction scores. Additional features (10%) included perks like international roaming, streaming bundles, and device trade-in values. All data reflects conditions as of early 2027.

1. T-Mobile πŸ† BEST OVERALL

T-MobileT-Mobile

T-Mobile is the dominant carrier in San Jose for 2027, leveraging its mid-band 5G spectrum (2.5 GHz) to deliver median download speeds of 286 Mbps in citywide tests. Its Ultra Capacity 5G covers over 95% of San Jose's population, including dense areas like downtown, Santana Row, and the Berryessa district. T-Mobile's Go5G Next plan at $70/month includes 50 GB of premium data before potential deprioritization, plus unlimited 4K video streaming and 10 GB of high-speed hotspot data.

For families, T-Mobile's Go5G Plus plan offers four lines for $120/month ($30/line) with Netflix Standard included. The carrier's Home Internet service, priced at $50/month, uses the same 5G network and delivers typical speeds of 150-300 Mbps in San Jose, making it a viable alternative to Xfinity. T-Mobile's Coverage Map shows strong signal along the 280 and 101 corridors, though fringe areas like the Santa Cruz Mountains may require a signal booster.

2. Verizon

VerizonVerizon

Verizon remains the reliability champion in San Jose, with 5G Ultra Wideband (mmWave and C-band) covering key commercial districts like downtown, the airport, and the SAP Center. Its median 5G speed of 162 Mbps is slower than T-Mobile's, but voice call reliability is 99.8% in San Jose, per RootMetrics 2026 data. Verizon's Unlimited Ultimate plan at $80/month includes 60 GB of premium data, 30 GB of hotspot, and Disney+ and Hulu bundles.

Verizon's 5G Home Internet at $45/month (with Auto Pay) offers speeds of 100-300 Mbps in eligible San Jose neighborhoods, though availability is limited compared to T-Mobile. The carrier's Visible prepaid brand provides the same network for $25/month with unlimited data, though speeds are capped at 200 Mbps during congestion. Verizon's Network Extender device can boost signal in homes with weak coverage, priced at $249.

3. AT&T

AT&TAT&T

AT&T offers strong coverage in San Jose's suburban neighborhoods like Willow Glen and Almaden Valley, with 5G+ (mmWave and C-band) available in downtown and the airport. Median 5G speeds are 134 Mbps, and voice reliability is 99.5%. AT&T's Unlimited Premium PL plan at $75/month includes 50 GB of premium data, 30 GB of hotspot, and HBO Max (now Max) ad-supported.

AT&T's Internet Air fixed wireless service costs $55/month and delivers 100-300 Mbps in select San Jose ZIP codes. The carrier's FirstNet priority service for first responders is a key differentiator, though not relevant for most consumers. AT&T's Trade-in offers are competitive, with up to $1,000 off the latest iPhone or Samsung Galaxy with eligible trade-in.

4. Mint Mobile πŸ’Ž BEST VALUE

Mint MobileMint Mobile

Mint Mobile, running on T-Mobile's network, is the best value carrier in San Jose for 2027. Its 12-month unlimited plan costs just $30/month (paid upfront), with 5 GB of hotspot data and 480p video streaming. Speeds are deprioritized after 35 GB of monthly usage, but in San Jose's dense urban areas, deprioritization is rarely noticeable.

Mint's 5 GB plan at $15/month (12 months) is ideal for light users who mostly use Wi-Fi. The carrier's Coverage Map mirrors T-Mobile's, so most of San Jose is well-covered. Mint's eSIM activation takes 5 minutes online, and the 7-day money-back guarantee reduces risk. The trade-off is no physical retail stores in San Jose, so support is via chat or phone.

5. Google Fi

Google FiGoogle Fi

Google Fi uses a multi-network approach, switching between T-Mobile, US Cellular, and Wi-Fi for optimal coverage in San Jose. Its Simply Unlimited plan at $50/month includes 35 GB of premium data and 5 GB of hotspot. Google Fi's Flexible plan at $20/month plus $10/GB is best for data-light users.

Google Fi's international roaming is a standout feature, with unlimited data at 256 Kbps in 200+ countries. In San Jose, coverage is excellent due to T-Mobile's network, but US Cellular's rural coverage adds value for trips to the Santa Cruz Mountains. Google Fi's Pixel Watch and Pixel Tablet bundles are available, but device selection is limited to Google and Samsung.

6. Visible (Verizon Prepaid)

Visible (Verizon Prepaid)Visible (Verizon Prepaid)

Visible, owned by Verizon, offers unlimited data on Verizon's 5G network for $25/month (Visible+ plan at $35/month). The base plan caps speeds at 200 Mbps and deprioritizes during congestion, but in San Jose's dense areas, speeds are typically 50-150 Mbps. The Visible+ plan adds 50 GB of premium data and 5G Ultra Wideband access.

Visible's Party Pay feature lets groups of four reduce the base plan to $20/month per line. The carrier's eSIM activation is instant, and the Watch plan for smartwatches costs $5/month. Visible's Coverage Map matches Verizon's, so San Jose's downtown and suburbs are well-covered. The downside is no physical stores and chat-only support.

7. Cricket Wireless (AT&T Prepaid)

Cricket Wireless (AT&T Prepaid)Cricket Wireless (AT&T Prepaid)

Cricket Wireless, running on AT&T's network, offers unlimited data for $55/month (Auto Pay) with 15 GB of hotspot and 480p video. The $60/month plan includes 30 GB of hotspot and AT&T 5G+ access. Cricket's Coverage Map shows strong signal in San Jose's suburban areas like Cambrian Park and Evergreen.

Cricket's 5 GB plan at $30/month is a solid budget option. The carrier's physical stores in San Jose (e.g., at 1010 E Capitol Expy) provide in-person support. Cricket's device selection includes budget phones like the Moto G Power for $49.99 with port-in. The trade-off is deprioritization during peak hours, which can reduce speeds in crowded areas like the San Jose State University campus.

8. US Mobile

US MobileUS Mobile

US Mobile offers customizable plans on both Verizon's (Warp 5G) and T-Mobile's (GSM 5G) networks. Its Unlimited Premium plan at $44/month includes 100 GB of premium data, 50 GB of hotspot, and 10 GB of international roaming. US Mobile's Build Your Own plan starts at $10/month for 2 GB.

US Mobile's pooled plans for families (e.g., 4 lines with 10 GB each for $65/month) are a strong value. The carrier's eSIM activation is quick, and its Coverage Map lets users choose the best network for their San Jose ZIP code. US Mobile's customer service is highly rated on Reddit, with 24/7 live chat support.

9. Boost Mobile (Dish Network)

Boost Mobile (Dish Network)Boost Mobile (Dish Network)

Boost Mobile, now owned by Dish Network, uses T-Mobile's network in San Jose while Dish builds its own 5G network (Project Genesis). Boost's Unlimited plan at $25/month includes 30 GB of premium data and 12 GB of hotspot. The $50/month plan adds 50 GB of premium data and Amazon Prime included.

Boost's Coverage Map shows strong T-Mobile coverage in San Jose, but Dish's native network is limited to select areas like downtown. Boost's physical stores (e.g., at 1600 Saratoga Ave) offer in-person support. The trade-off is deprioritization on T-Mobile's network, which can be noticeable during peak times.

10. Xfinity Mobile (Comcast)

Xfinity Mobile's Coverage Map shows excellent Verizon coverage in San Jose. The carrier's device deals are competitive, with $500 off the latest iPhone for new lines. The downside is deprioritization after 20 GB of monthly usage on the unlimited plan. Xfinity Mobile's Wi-Fi hotspots in San Jose (e.g., at coffee shops and malls) can offload data usage.
