Can You Really Upgrade a 4G Android Phone to 5G?

 A 4G Android phone cannot be natively upgraded to 5G because 5G requires specific hardware—a 5G modem—built into the device. However, you can access 5G-like speeds through workarounds like 5G hotspots and routers. For a true 5G experience, upgrading to a 5G-compatible smartphone is the most reliable option.

Let’s be honest—5G is everywhere right now. Carriers are rolling it out across cities, phone manufacturers are making it their headline feature, and everyone seems to be talking about lightning-fast download speeds and ultra-low latency. So it makes total sense that you’d want in on the action!

But here’s the question a lot of Android users are asking: can I upgrade my existing 4G phone to 5G without buying a new device? The short answer is no—but there’s more to the story. There are some clever workarounds that can get you closer to that next-gen connectivity experience, and it’s worth knowing exactly what your options are before spending any money.

This guide breaks it all down—from why 4G and 5G aren’t compatible at the hardware level, to practical solutions you can try today.

What Makes 5G Different From 4G at a Hardware Level?

5G delivers significantly faster speeds, lower latency, and greater network capacity than 4G LTE. According to Qualcomm, 5G peak speeds can reach up to 20 Gbps, compared to around 1 Gbps for advanced 4G networks. Impressive, right?

But here’s the catch: accessing 5G requires a 5G modem chip inside your phone. This modem is responsible for connecting your device to 5G radio frequencies—including Sub-6 GHz and mmWave bands. No 5G modem means no 5G connection, full stop.

Unlike software, which can be updated remotely, hardware is fixed at the point of manufacture. If your Android phone was built with a 4G LTE modem, that’s what it will always have. There’s no software patch, firmware update, or SIM card swap that changes this.

How to Check if Your Android Phone Supports 5G

Before assuming your phone is 4G-only, it’s worth double-checking! Here’s how:

• Go to Settings > About Phone > Specifications and look for network compatibility details.
• Search your phone model on your carrier’s website to see if 5G is listed as a supported network.
• Visit GSMArena.com and search your device—it lists every network band your phone supports.

If 5G isn’t listed anywhere, your phone is 4G-only. Simple as that.

Can You Get 5G Speeds on a 4G Phone? (Workarounds Explained)

Even without a 5G modem, there are a few ways to access faster internet speeds through external devices. None of these are a true upgrade—but they can make a real difference depending on your situation.

Using a 5G Mobile Hotspot or Router

This is the most popular workaround, and honestly, it works really well! A 5G mobile hotspot (like the Netgear Nighthawk M6 or the T-Mobile 5G Internet Gateway) connects to 5G networks independently and then shares that connection with your 4G phone via Wi-Fi.

Your phone doesn’t need a 5G modem for this—it just connects to the hotspot like any other Wi-Fi network. You won’t get native 5G integration, but you can still benefit from much faster download and upload speeds.

Best for: People who work from home, travel frequently, or live in areas with strong 5G coverage but weak Wi-Fi.

Exploring 5G Network Extenders and Repeaters

Some carriers offer 5G signal extenders that boost 5G coverage within your home or office. However, your 4G phone still connects to these via Wi-Fi or LTE—not directly through a 5G modem. The benefit here is improved signal quality and speed in areas where your current 4G connection is weak.

Best for: Users in suburban or semi-rural areas with inconsistent signal.

Cloud-Based Speed Solutions

Some apps and platforms claim to boost internet performance by optimizing how your device connects to servers—think VPN-based acceleration tools or CDN-enhanced browsers. These can modestly improve page load times, but they do not add 5G connectivity. Be skeptical of any app that claims to “enable 5G” on a 4G phone—that’s simply not how wireless technology works.

What to Think About Before Buying an External 5G Device

External solutions aren’t free, and they come with trade-offs. Here’s what to weigh before opening your wallet:

• Cost: A quality 5G hotspot device can range from $100 to $400+, plus a separate data plan from your carrier. Over 12 months, this can add up quickly.
• Coverage: 5G coverage is still expanding. Check your carrier’s 5G map before investing—there’s no point paying for 5G if it doesn’t reach your area yet.
• Battery impact: Running your phone connected to a hotspot constantly drains your battery faster than usual. If you’re out and about, you’ll want a power bank on hand.
• Data plan: Most 5G hotspot plans have data caps or throttling policies. Read the fine print carefully before committing.

Practical Ways to Maximize Your Current 4G Performance

If a hotspot isn’t in your budget right now, there’s still plenty you can do to squeeze more performance out of your existing 4G connection:

• Switch network modes manually: Go to Settings > Connections > Mobile Networks > Network Mode and select “LTE/4G” to prioritize the fastest available signal.
• Reset your APN settings: Incorrect Access Point Name (APN) settings can slow your connection. Contact your carrier for the correct settings.
• Update your carrier settings: Carriers push periodic updates that optimize network performance. Check for these in your phone’s settings.
• Reduce background data usage: Apps running in the background consume bandwidth. Restrict background data for apps you don’t need constantly syncing.

These tweaks won’t give you 5G, but they can noticeably improve your everyday browsing, streaming, and download experience.

Is It Time to Consider a New 5G Smartphone?

Here’s the honest truth: if you want a genuine 5G experience, a new 5G-enabled Android smartphone is the most straightforward path. The good news? 5G phones have become much more affordable. Devices like the Motorola Moto G 5G and Samsung Galaxy A54 5G offer 5G connectivity at mid-range prices, often starting under $400.

When shopping for a 5G Android phone, check for:

• Support for both Sub-6 GHz (wider coverage) and mmWave (ultra-fast, shorter range) bands
• A 5G-compatible processor like the Snapdragon 7 Gen 2 or Dimensity 900
• Compatibility with your specific carrier’s 5G network bands

It’s also worth waiting for carrier deals—major providers like AT&T, Verizon, and T-Mobile regularly offer trade-in promotions that can significantly reduce the cost of upgrading.

The Future of 5G and What It Means for You

5G is still in its expansion phase. According to the GSM Association (GSMA), 5G connections are expected to reach 5.9 billion globally by 2030—making it the dominant mobile technology within this decade. As coverage expands and device prices drop, the barriers to entry will only get lower.

For now, use the workarounds if they make sense for your budget and lifestyle. Optimize your current 4G connection for the best performance possible. And when the time is right—whether that’s a great trade-in deal or a carrier promotion—make the switch to a 5G device. You’ll notice the difference immediately!

The bottom line? Your 4G Android phone can’t truly become a 5G phone. But that doesn’t mean you’re stuck. You’ve got options—and now you know exactly which ones are worth your time.

Frequently Asked Questions

Can I add a 5G modem to my existing 4G Android phone?

No. 5G modems are integrated into a phone’s chipset during manufacturing and cannot be added externally or retrofitted after the fact. The only way to get native 5G support is to purchase a device built with a 5G-compatible processor.

Will a new SIM card give my 4G phone access to 5G?

No. A 5G SIM card enables your account to access 5G services, but your phone still needs a 5G modem to connect to those networks. Without the modem, the SIM card makes no difference to your network speed.

What’s the cheapest way to experience 5G without buying a new phone?

The most affordable option is a 5G mobile hotspot device. Entry-level models are available from carriers for under $100 with a qualifying plan, though you’ll pay an additional monthly fee for a separate data plan.

Does 5G drain battery faster than 4G?

Yes, 5G typically consumes more battery than 4G, especially on mmWave networks. However, manufacturers have improved efficiency significantly in newer chipsets. If battery life is a concern, most 5G Android phones allow you to switch between 5G and LTE modes manually to conserve power.

Is 5G coverage good enough to justify upgrading right now?

It depends on where you live. Major metro areas in the US generally have strong Sub-6 GHz 5G coverage. Rural areas, however, may still rely heavily on 4G LTE. Check your carrier’s coverage map at your home and workplace before committing to an upgrade.
