5G Check: Phone 5G Support

5G Check inspects what your handset's radio can do and what your carrier is currently giving you, then tells you which of the two is holding you back. It separates the three things people usually confuse: whether the hardware supports 5G at all, whether your plan and SIM have it switched on, and whether you're actually connected to it this second.

What it does

• Device 5G hardware capability
• Live network registration — 5G, LTE or below
• Distinguishes 5G NSA from standalone 5G
• Carrier and SIM readiness
• Plain-language verdict, not a wall of raw fields
• No account, no sign-in, no setup

Common questions

Written by us, and answerable without installing anything.

• Why your phone keeps switching from 5G to 4GSwitching between 5G, 4G and 4G+ is almost always normal, not a fault. What triggers each switch, why 4G+ is not a halfway state, and the one pattern that is.
• How to check whether your phone supports 5G5G support is not one capability — it is a list of bands, an architecture, and a carrier's approval of your exact model. Here is how to check each, and why the box saying 5G is not enough.
• How to enable 5G — and why it may not appear at allThe 5G setting on Android, and the three separate things that must all be true before it shows up — device bands, carrier provisioning, and whether 5G has actually reached your area.
• No 5G in your area? How to tell whose fault it isThree separate things have to be true before 5G appears — coverage where you stand, a phone with the right bands, and a plan that includes it. Here is how to work out which one is missing.
• eSIM vs physical SIM — what actually changesAn eSIM is the same SIM, soldered in and provisioned over the air. That single difference is what makes it better for travel and worse when you break your phone.
• 5G bands explained — n78, n41, n71 and why they decide your speedWhich 5G bands your phone supports matters more than whether it supports 5G at all. A reference to the bands in common use, what each is good for, and why imported handsets so often disappoint.
• Why 5G drains your battery, and what to do about itNon-standalone 5G runs two radios at once, and weak signal costs more power than fast signal saves. Here is what is actually consuming the charge and which settings are worth changing.
• 5G NSA vs SA — what the difference actually means for youNon-standalone 5G rides on a 4G network. Standalone 5G runs on its own core. That one architectural difference explains latency, battery life, and why your 5G sometimes feels no faster than LTE.
• Your phone says 5G but the speed is slow — here is whyA 5G icon tells you almost nothing about the speed you will get. Band, bandwidth, congestion, plan priority and thermal throttling all matter more, and most of them are invisible from the status bar.
