Backup Internet Options: Hotspot, 5G Home, Starlink or a Second ISP

The cheapest backup for a home internet outage is the hotspot on your phone, which usually costs nothing extra if your plan includes hotspot data. If you work from home or lose internet often, a second connection on different equipment, such as 5G home internet, Starlink or a second wired provider, keeps the whole household online for longer. Pick the backup that does not share the weak point of your main connection.

Which backup internet option fits my home?

The table compares the five common choices. Prices are from the providers’ official plan pages as of November 2026 and depend on your address.

Option	Cost as of November 2026	Ready in	Fails together with	Best for
Phone hotspot	Often included in your phone plan; Verizon lists an Unlimited Hotspot add-on at $15 a month per line	Seconds	Your cell carrier’s network	Short outages, one or two laptops
5G home internet	Verizon 5G Home $60 to $85 a month, or $35 to $60 with Auto Pay and a Verizon phone plan; AT&T Internet Air from $55 a month with AutoPay and paperless billing	A few days (a router ships to you)	Cell towers near your home	Remote work, a whole household
Starlink	A kit bought up front plus a monthly plan; prices for your address on starlink.com	A few days (a dish ships to you)	A blocked view of the sky, loss of home power	Rural homes, storms that cut local lines
Second wired provider	A second full monthly plan	Days to weeks (installation)	Shared poles, trenches and street power	Home businesses that cannot go offline
Your provider’s own backup	Xfinity Storm-Ready WiFi; AT&T Internet Backup for customers who bundle home internet and wireless	A few days	Problems inside the same company	Automatic switchover without extra setup

Before you buy anything, confirm the outage is real and not your router. Our guide to finding why the internet is down at home walks through the checks.

Is a phone hotspot enough as backup internet?

For most homes, a phone hotspot is enough for an outage of a few hours. It handles email, web pages and usually a video call if the cell signal is good.

To turn it on:

1. iPhone: go to Settings > Personal Hotspot, or Settings > Cellular > Personal Hotspot, and turn on Allow Others to Join. Apple’s Personal Hotspot help page also covers USB and Bluetooth connections.
2. Android: swipe down from the top of the screen, touch and hold Hotspot, then turn on Wi-Fi hotspot. Menu names can differ by phone maker.
3. Connect the laptop to the phone’s network name and enter the hotspot password shown on the phone.

The limits are worth knowing before an outage:

• Hotspot data caps. Many plans include a set amount of high-speed hotspot data per month. After that, speed drops. Verizon’s Unlimited Hotspot add-on, for example, slows to up to 4 Mbps after 200 GB in a billing cycle.
• Battery. Tethering drains a phone quickly. Keep it plugged in, as Google’s Android help also advises.
• Carrier rules. Apple and Google both note that some carriers restrict hotspot use or charge for it.
• Shared failure. If your carrier has an outage, the hotspot fails too. A second phone in the house on a different carrier gives you a fallback. Check live Verizon status or live AT&T status if the hotspot will not connect, and see how to tell if your phone carrier is down.

Is 5G home internet a good backup?

5G home internet is a good backup when your address gets a strong signal and your main service is cable, fiber or DSL. It uses cell towers instead of the wires in your street, so a cut cable line does not take it down.

The tradeoff is cost. You pay for a full monthly plan that sits mostly unused. Some households flip the setup: they use 5G home internet as the main connection and keep a cheaper wired plan, or the reverse. Verizon’s plan page lists price locks of 3 to 5 years and requires you to return the router within 30 days if you cancel. AT&T’s Internet Air page notes that speeds can be reduced during network congestion, which matters if many neighbors switch to cellular during the same outage.

When does Starlink make sense as backup internet?

Starlink makes sense when local lines and towers are the problem, for example in rural areas or after storms that bring down poles. The dish talks to satellites, so it does not depend on the cable or fiber in your street. Check live Starlink status when the dish reports no connection.

Three limits apply. The dish needs a clear view of the sky. You pay for the hardware up front, unless a promotion covers it. And the dish and router need power, so in a power outage they need a battery or a generator. Starlink lets you pause service; check the current pause and Standby Mode terms and price in the Starlink app or on starlink.com before you count on a paused dish as your backup.

Is a second wired internet provider worth it?

A second wired provider is worth it only if both services are truly separate, such as cable from one company and fiber from another. Two lines that run on the same poles can fail together when a pole comes down or a street loses power.

This is the most expensive choice: two full bills, two installations and often a router with dual-WAN failover, which switches to the second line by itself. Without that router, you switch networks by hand. For most homes, a hotspot or 5G home internet covers the same need for less.

Does my internet provider offer a built-in backup?

Some providers sell or include a backup that switches over automatically:

• Xfinity Storm-Ready WiFi. Comcast’s August 2023 launch announcement describes a device with a battery that lasts up to four hours and a cellular backup with unlimited data during outages, priced then at $7 a month for 36 months. Check the current price with Xfinity, and see live Xfinity status during an outage.
• AT&T Internet Backup. AT&T’s June 3, 2026 announcement says Internet Backup switches service to wireless when AT&T Fiber goes down, and that customers who bundle home internet and wireless get it free.

Ask your own provider whether it offers something similar. A backup from the same company does not protect you from a problem inside that company’s network.

How do I switch to backup internet during an outage?

1. Confirm the outage on your provider’s outage page or app, using mobile data.
2. Turn on the backup: the phone hotspot, or the 5G or Starlink router.
3. Connect only what you need. Work laptops first, streaming TVs last.
4. Pause heavy traffic: cloud backups, photo uploads, game downloads and system updates.
5. Keep the backup powered. Plug in the phone, or put the router on a battery. Our guide to keeping your router running in a power outage explains sizing.
6. Switch back when the main service returns, then check whether you qualify for an outage credit from your provider.

Bottom line

Start with your phone hotspot and learn its data limit before you need it. Add 5G home internet or Starlink if you work from home or lose service often, and choose the one that does not share your main line’s weak point. A second wired provider is mainly for home businesses.

FAQ

Can I use my phone hotspot for work video calls?

Usually, yes, if the cell signal is good. Video calls use far more data than email, so watch your plan’s high-speed hotspot allowance.

Does 5G home internet or Starlink work in a power outage?

Only if the router or dish has power. Both plug into the wall, so they need a battery backup, a portable power station or a generator.

Can I cancel a backup plan after the outage?

It depends on the plan. AT&T says Internet Air has no annual contract, and Verizon lists a 30-day money-back guarantee for 5G Home with some exclusions. Read the terms before you sign up.

Will a backup from the same provider help?

It helps when the problem is your line or your street. It may not help when the provider’s wider network is down, because both connections depend on the same company.
