Now that 5G networks are switching on across Pakistan and running widely in India, the same question keeps coming up: can I change my 4G phone to 5G? The answer depends entirely on what is inside your handset, and most articles on this subject blur that line on purpose.
Here is the direct version. If your phone was built with a 5G modem, you can change 4G to 5G in the network settings in under a minute. If it was not, no app, code, setting or SIM swap will create 5G for you. This guide covers both situations: how to switch your phone over properly, how to confirm what hardware you actually have, and why a 5G-capable phone sometimes still refuses to show the 5G icon.
Why a 4G-only phone cannot become 5G
Mobile network generations are built into the chipset. A phone needs a modem that understands 5G radio signals, plus antennas tuned to the frequencies your operator uses. That hardware is soldered in during manufacturing.
Software can switch features on or off, but it cannot add a radio that was never installed. This is the same reason a 3G phone could not be updated into a 4G phone a decade ago. The limitation is physical, not a restriction someone imposed on you.
There is one narrow exception worth knowing. A few phones ship with 5G hardware inside while the feature stays inactive until the model passes local network certification. In those cases a system update from the manufacturer switches it on. That is an unlock of existing hardware, not a conversion of a 4G phone.
What “4G to 5G converter” apps actually do
Search any app store and you will find listings promising to convert 4G into 5G, usually with a speedometer icon and huge download counts. None of them deliver what the name suggests.
Most fall into three groups:
- Shortcut apps that simply open the network mode menu already built into Android
- Ad wrappers that display a fake loading animation and serve advertisements
- Junk cleaners that claim clearing cache will boost your connection speed
The third type is the one to avoid most carefully, since several of these apps request broad permissions that have nothing to do with network settings. If an app asks for contacts, SMS or accessibility access to change a connection setting, uninstall it.
How to check whether your phone supports 5G
Three quick checks settle this. Any one of them is enough.
- Look in settings. Open Settings, then Network & internet or Connections, then Mobile network or SIMs, then Preferred network type. If 5G appears in the list, the hardware is there.
- Check the model number. Find it under Settings, About phone. Search that exact model on a device database such as GSMArena and look at the network row. Marketing names can be misleading, so use the model code rather than the name printed on the box.
- Check your operator’s device list. Regulators require operators to publish which handset models are supported on their 5G networks, and those lists are on the official operator websites.
Buying second-hand or importing from another country adds a trap here. Some regional variants of the same phone ship with different band support, so two handsets with the same name can behave very differently on the same network.
How to change 4G to 5G on Android
Once the hardware is confirmed, the switch itself is simple. Menu names vary slightly between brands, but the path is consistent.
- Open Settings.
- Tap Network & internet on stock Android, or Connections on Samsung devices.
- Select SIMs or Mobile networks, then choose the SIM you want to use for data.
- Tap Preferred network type or Network mode.
- Select the option that includes 5G, usually listed as 5G/4G/3G/2G auto.
- Toggle aeroplane mode on and off, or restart the phone, so it registers again on the network.
On Xiaomi, Realme, Infinix, Tecno and vivo devices the wording differs but the sequence is the same. Some phones also hide a separate toggle simply labelled Enable 5G inside the SIM settings, so check there if the network mode list looks incomplete.
Dual SIM users should note that many phones run 5G on only one SIM slot at a time. If your data SIM sits in the secondary slot, move it or change the data SIM assignment.
Bands: why a 5G phone can still stay on 4G
This is the detail that frustrates people most. A phone can be genuinely 5G-capable and still never show 5G, because it does not support the frequency bands your operator actually uses.
In Pakistan, operators secured spectrum in the 700, 2300, 2600 and 3500 MHz ranges during the 2026 auction, with the 3500 MHz band doing most of the heavy lifting for 5G speed. Indian networks lean heavily on the same 3.5 GHz range along with 700 MHz for coverage. In 5G band naming, those correspond to n78, n41, n40 and n28.
If your handset lists only mmWave bands or bands used in other markets, it will connect over 4G here regardless of what the box says. Check the supported band list before buying, particularly with imported or grey-market phones.
Do you need a new SIM or a new package?
Usually no. Modern 4G SIM cards generally work on 5G networks without replacement, and in Pakistan existing 4G data bundles have been working on the new 5G networks without a separate subscription. Very old SIMs issued years ago are the exception and may need a free replacement at a service centre.
Coverage is the bigger variable. Rollout is still concentrated in major cities, and as of September 2026 the combined national 5G footprint remains in the low thousands of sites. Outside those areas, a 5G phone with perfect settings will still sit on 4G because there is nothing to connect to.
Still showing 4G? Run through this list
| Requirement | How to verify |
|---|---|
| 5G modem in the phone | 5G appears in the network type menu |
| Correct band support | Model specifications list n78, n41, n40 or n28 |
| 5G coverage in your area | Operator coverage map or checker |
| Network mode set correctly | Preferred network type includes 5G |
| Updated software | Settings, System, Software update |
| Correct SIM slot selected | Data SIM assigned to the 5G-capable slot |
If everything on that list checks out and 5G still does not appear, contact your operator. Some models need to be activated on the network side before the icon shows.
What the upgrade actually feels like
Expect faster downloads and noticeably lower lag on video calls and gaming when you are within range of a 5G site. Do not expect the advertised peak figures, which are laboratory numbers measured with no other users on the tower.
Battery life is the trade-off. Searching for and holding a 5G signal at the edge of coverage drains more power than staying on 4G. If your battery drops sharply after switching, set the network mode back to 4G when you do not need the extra speed. Because early 5G deployments frequently rely on 4G as an anchor layer, you will also see the connection switch between the two as you move around, which is normal.
While you are in the network settings, it is worth reviewing your lock screen too, since recovering a phone you are locked out of is far harder than preventing it. Our guide on how to unlock an Android pattern lock explains what works and what does not.
Frequently asked questions
Is there a code or secret menu to enable 5G on a 4G phone?
No. Dialler codes open engineering menus that display existing radio settings. They cannot add hardware that is not present, and changing values there can break your mobile data.
Will a system update turn my 4G phone into a 5G phone?
Only if the phone already contains a 5G modem that was waiting on certification. If the specifications say 4G, no update will change that.
Why does my phone show 5G but the speed feels the same as 4G?
Signal strength, tower congestion and the band in use all affect real speed. A weak 5G signal on a low band can easily perform worse than a strong 4G connection.
Does keeping 5G enabled use more data?
Not by itself. Data use rises because faster connections encourage higher video quality and larger downloads, so check your streaming quality settings after switching.
Should I buy a 5G phone if my area has no 5G yet?
If you are replacing your phone anyway, a 5G model with the right bands is sensible future-proofing. Upgrading a working phone purely to reach a network that has not arrived is harder to justify.
Where to go from here
Start by opening your network settings and looking for a 5G option. If it is there, switch it on, restart, and you are done. If it is not, your phone is 4G-only, and the practical decision becomes whether local coverage justifies a new handset yet. When you do buy, check the supported bands against the ones your operator uses rather than trusting the 5G label on the packaging, as licensing details and coverage information are published by the Pakistan Telecommunication Authority and the operators themselves.
