If you find 5g not working on your phone, the cause is usually one of four things: your phone cannot use the 5G bands in India, the setting is stuck on 4G, your area has no 5G tower yet, or your plan does not include 5G. Seeing a 5G label does not always mean fast internet either.
Many readers write "my network is showing 5G but not working". That happens when the phone connects to a tower but the data session behind it is broken or the tower is crowded. This guide helps you tell those cases apart and fix what you can on your side.

What fixes itChange the preferred network type to the 5G option in mobile network settings
2Phone does not support the 5G bands used here
How to tellPhone has a 5G label on the box but friends with other models get 5G
What fixes itCheck the phone's supported bands and update its software; ask the shop if unsure
3No 5G coverage at your spot
How to tell5G appears outdoors or in some rooms only
What fixes itMove near a window or outside, and try again
4Plan or SIM is not eligible
How to tell4G works, 5G never appears while others on the same tower have it

55G icon shows but data session is stuck
How to tellFull bars and 5G, yet pages will not load
What fixes itTurn airplane mode on and off, or switch to 4G for a while
6Tower is crowded
How to tellSpeed drops badly at evenings or in busy places
What fixes itTry another time or place; nothing to fix on the phone
7Old software or a wrong carrier setting
How to tell5G worked earlier and stopped after a reset or SIM change
What fixes itUpdate the system software and restart the phone
How to fix it, step by step
Confirm 5G is really selected
On most Android phones, find your SIM under the mobile network settings (the exact menu name varies by brand) and open Preferred network type. Pick the entry with 5G in its name. On iPhone, go to Cellular, then Cellular Data Options, then Voice and Data, and choose 5G Auto or 5G On.
Check each SIM slot on a two-SIM phone
A lot of handsets give 5G to only one slot at a time. If your 5G SIM sits in the second slot, the phone may use 4G there. Move the SIM to the slot marked for 5G or set it as the data SIM in the SIM manager.
Go outside or near a window
5G signal gets weaker through thick walls and basements. Stand outside or near a window for a minute and watch the status bar. If 5G appears there, your area has coverage and only the indoor signal is weak.
Switch airplane mode on for 20 seconds
Airplane mode forces the phone to search again for the best network. Turn it off and give the phone half a minute. This often moves a phone stuck on 4G back to 5G.
Restart the phone
A full restart clears many radio glitches. After the phone starts, wait for the signal to settle before testing.
Update the phone software
5G support often arrives or improves in software updates. Open Settings, then System update (or General, then Software Update on iPhone) and install what is waiting. Keep the phone on Wi-Fi and charged while it installs.
Re-seat the SIM and check its age
Switch the phone off, take the SIM out, wipe it dry with a clean cloth and put it back. An old 4G-era SIM card can still work, but if you have used the same SIM for many years and 5G never shows, ask the store about a swap.
Reset network settings
If nothing helped, use the reset option for mobile and Wi-Fi settings. Saved Wi-Fi logins and Bluetooth pairings are lost, but photos and apps stay. Pick the 5G network type again afterwards.
How to check 5G is working or not
The 5G symbol only tells you which kind of tower the phone is attached to. To check real working, do three things. Open a speed test app or site and note the result. Open a large video and see if it plays without stopping. Then compare with the same test after switching the network type to 4G. If 5G is not faster, either the tower is crowded or your plan is slowing you.
The status bar shows 5G with full bars, yet a web page takes a minute to open. Turn airplane mode on and off. If it still crawls, switch to 4G for the evening and try 5G again in the morning.
Unlimited 5G data not working
Plans with unlimited 5G usually have conditions: the plan must be of a certain size, the phone must be 5G capable, and you must be inside a covered area. Some plans only unlock 5G after a recharge is active, or after you opt in through the operator's app. If you have unlimited 5G data but nothing works, check three things: that your plan is active, that 5G is listed on the plan details, and that your daily 4G data has not simply ended. Do not guess codes or dial random numbers; use the operator's app for plan details.
5G network not working: phone, SIM or tower
| Test | If this happens | Likely fault |
|---|---|---|
| Try your SIM in a friend's 5G phone | 5G appears | Your phone settings or bands |
| Try a friend's SIM in your phone | 5G appears | Your SIM or plan |
| Neither shows 5G in your room | 5G appears outside | Weak indoor coverage |
| Nobody nearby has 5G | Same on other phones | Tower not ready in the area |
If you only lose speed and not the 5G label, read mobile data not working instead. For problems tied to one provider, see the guides on 5G on that provider's SIM and unlimited 5G plans.
Why 5G is not working today, and 5g not working in your area
If 5G stopped suddenly, ask someone nearby on the same network whether they still have it. Check the provider's official social account or app for notices. If others have it and you do not, the fault is on your phone or SIM. If nobody has it, wait a few hours; tower work or a fibre cut is usually fixed by then.
When to visit the store or a repair shop
Go to the operator's store if the SIM is old, 5G is missing on every phone you try, or the plan details do not mention 5G. Go to a repair shop if the phone has lost signal entirely after a fall or water contact, since the antenna or modem could be damaged. A software fix costs little; antenna or board repair costs more.
Rooting or flashing unofficial software to "unlock" 5G can void your warranty and break calling. Use only official updates.
Frequently asked questions
Why is my 5G network not working on my phone?
Most often the network type is set to 4G, the phone lacks the bands used here, or there is no 5G coverage where you stand. Check the setting first, then go outdoors and restart the phone.
My phone shows 5G, so why is the internet dead?
The icon shows the tower type, not the health of the data session. Turn airplane mode on and off, or switch to 4G for a while. If it keeps happening, check balance and plan validity.
Why is my 5G unlimited data not working?
Unlimited 5G needs a qualifying plan, a 5G phone and coverage at your spot. Confirm the plan is active in the operator's app and that your area is covered.
Does every 5G phone work on every network?
No. Phones support different 5G bands, and a phone that lacks the bands used here may stay on 4G. Check the model's band list before buying and keep the software updated.
Why 5G is not working in my phone only at home?
Test outside and near a window. If 5G appears there, indoor walls are weakening the signal. Keep the phone near a window or use home broadband for heavy use.
