With 5G rollout accelerating and unlimited mobile data plans becoming more affordable, many UK households are questioning whether they still need traditional home broadband. This guide compares mobile hotspots, 5G home broadband, and fixed-line broadband to help you choose the right solution.

What is a Mobile Hotspot?

Types of Mobile Hotspots

1. Phone Hotspot (Tethering)
– Uses your phone’s mobile data
– Share via WiFi, Bluetooth, or USB
– Most phones support 5-10 connected devices
– Free (uses existing phone plan data)

2. Dedicated Mobile Hotspot Device (MiFi)
– Standalone portable WiFi router
– Uses SIM card with data plan
– Longer battery life than phone (8-24 hours)
– Supports 10-30 devices
– Examples: TP-Link M7450 (£80), Netgear Nighthawk M6 (£400)

3. Dongles/USB Modems
– Plugs into laptop USB port
– Single-device connection only
– Cheaper than MiFi (£20-50)
– Less common in 2026 (hotspots more versatile)

How Phone Hotspot Works

iPhone Setup:

  • Settings → Personal Hotspot
  • Toggle “Allow Others to Join”
  • Note WiFi password
  • Connect other devices using password
  • Android Setup:

  • Settings → Network & Internet → Hotspot & Tethering
  • WiFi Hotspot → Turn On
  • Configure name/password
  • Connect devices
  • Battery Impact: Hotspot drains battery 3-5x faster. Keep phone plugged in for extended use.

    What is 5G Home Broadband?

    5G Home Broadband Explained

    How It Works:
    – Router connects to 5G mobile network (like phone)
    – Router plugs into wall socket (not portable like hotspot)
    – Broadcasts WiFi throughout home
    – No phone line or cables needed
    – No installation or engineer visit

    Key Difference from Hotspot:
    – Dedicated home router (not using phone)
    – Unlimited data (no caps)
    – Stronger signal (external antennas)
    – More simultaneous devices (30-50)
    – Optimized for home use (not battery-powered)

    Coverage Requirement: Must have 5G signal at your address (check provider coverage maps)

    When 5G Home is NOT Suitable

    ❌ Avoid If:

    1. Poor 5G Coverage at Your Address
    – Check Three/EE/Vodafone coverage maps

    Ping: 20-50ms
    Stability: 4/5 (dedicated router, better antennas)
    Best for: Home use, renters, quick setup

    Fixed Fibre (FTTC/FTTP):
    Download: 36-1,130 Mbps
    Upload: 10-110 Mbps (symmetrical on full fibre)
    Ping: 10-30ms
    Stability: 5/5 (most reliable)
    Best for: Long-term, multi-user, heavy use

    Latency Matters For:

    Gaming (Competitive):

    Video Conferencing:
    – Need: <50ms – All options work, but fixed fibre most reliable

    Streaming:
    – Latency less important
    – All options fine if speed sufficient

    Reliability and Data Limits

    Connection Stability

    Most Reliable → Least Reliable:

  • Fixed Fibre (FTTP): 99.9% uptime, weather-proof, no congestion
  • Fixed Copper (FTTC): 99% uptime, can be affected by rain/distance
  • 5G Home Broadband: 95-98% uptime, affected by weather/congestion
  • Mobile Hotspot: 90-95% uptime, battery limitations, signal dependent
  • Data Limits Reality

    Mobile Hotspot:
    – Capped plans (20-100GB): £8-15/month
    – Unlimited plans: £10-20/month
    Risk: “Unlimited” may have fair usage policies (read terms)
    – Three: Truly unlimited (no cap)
    – Others: May throttle after 600GB-1TB

    5G Home Broadband:
    – All providers: Unlimited data
    – No fair usage policies (as of Jan 2026)
    – Three, EE, Vodafone all truly unlimited

    – No caps, no throttling
    – Use as much as you want

    Frequently Asked Questions

    Q: Can I use my phone hotspot as full-time home internet?
    A: Technically yes, but not recommended. It drains battery, struggles with multiple devices, and may exceed data caps. Use 5G home broadband (£21/mo) instead.

    Q: Is 5G home broadband as fast as fixed fibre?
    A: Similar for most use. 5G: 100-300 Mbps typical. Fixed fibre: 150-1,130 Mbps. For everyday use (streaming, browsing), both are sufficient.

    Q: Does mobile hotspot work for Netflix?
    A: Yes for HD (10 Mbps needed). 4K uses 7GB/hour—only do this with unlimited data plan. Fixed broadband or 5G home better for daily streaming.

    Q: Can I game on mobile hotspot?
    A: Casual gaming: yes. Competitive gaming (CoD, Valorant): no. Latency too high (30-80ms vs 10-20ms on fibre). Use fixed fibre for competitive play.

    Q: What’s the cheapest internet option for renters?
    A: Three 5G Home Broadband at £21/month (1-month rolling, no installation, portable). Perfect for short-term rentals.

    Q: Will mobile hotspot work in rural areas?
    A: Depends on coverage. Check 4G/5G signal strength at your address. If signal is strong, yes. If weak, fixed broadband (FTTC/FTTP) more reliable.

    Q: Can I work from home using mobile hotspot?
    A: Light work (email, documents): yes. Heavy work (video calls, large file uploads): not ideal. Use 5G home broadband (£21/mo) or fixed broadband (£26+/mo) instead.

    Q: Is Three 5G really unlimited?
    A: Yes. Three’s unlimited plans are truly unlimited—no fair usage caps or throttling (as of January 2026). Best for hotspot and home broadband use.


    Bottom Line: Mobile hotspots are perfect for backup, travel, and very light home use but cannot replace home broadband for most households. 5G home broadband (Three £21/mo) is the ideal middle ground—offering broadband speeds with mobile flexibility, perfect for renters and quick-setup needs. Fixed-line broadband remains best for long-term residents, heavy users, gamers, and multi-person households, with the most reliability and lowest cost per Mbps over time.

    Quick Decision Guide:
    Backup/travel internet: Mobile hotspot (Three Unlimited SIM £10/mo)
    Renter (short-term): 5G home broadband (Three £21/mo)
    Light use (single person): 5G home (Three £21/mo) or NOW Broadband (£26/mo)
    Family/heavy use: Fixed broadband (Virgin £30/mo, BT £36/mo, TalkTalk £27/mo)
    Gamer: Fixed fibre (Community Fibre £25/mo, Hyperoptic £26/mo)
    Homeowner (long-term): Fixed broadband 150+ Mbps (£25-36/mo)


    Pricing verified December 2025/January 2026. Prices subject to mid-contract increases (typically CPI+3.9% each April). Check coverage for 5G home broadband at your specific address before ordering.
