iPhone 17e 5g signal reception problem indoor

If the 5G signal isn't strong in the area of your house, your phone will struggle to connect or remain connected to it. That's not something anyone here, nor at Apple can assist you with. That's the carriers signal and your proximity to it where you are. A better option is to Choose 5G Auto in Settings > Cellular > Cellular Data Options and your phone will choose the strongest band where you are located. Or use Wifi Calling, which is another carrier provided feature, which will use Wifi as opposed to cellular if it will provide a more stable connection.

So admittedly, even your iPhone 15 get's poor 5G connectivity in the same location. It's still not an issue with either iPhone. It's simply the poor 5G signal in that location. Again, that's not something anyone on this user to user only forum can resolve. Even Apple can't resolve such an issue. It's the signal you're getting from your carrier.

Simply said, the cellular radio in your iPhone can't improve the signal from your carrier. You might want to look at a different carrier if you're not getting as strong a connection as you want from the carrier you are using.

3G/LTE/LTE+/4G use radio frequencies that penetrate structures somewhat better than some of the other frequencies that can be used for 5G.

Carriers can have their own and creative definitions of their particular “G” naming scheme, too.

5G (usually) has more capacity and performance and lower latency, and supports much higher deployment and client densities, supports mmWave for high density and high bandwidth, and 5G will usually be preferred where coverage can be maintained.

How carriers adjust their 5G frequency usage (low, mid, mmWave, etc) for deployment density or for wider coverage with fewer towers varies by carrier and by individual towers, too.

For your coverage concerns? Consider adding a picocell or femtocell, or Wi-Fi offload, if your carrier supports any of that.

As for why a particular band switch happens (or not) with a particular carrier and particular phone and particular tower, donno.

I don't know why either, but it wouldn't be something which I'd be concerned about. To be honest, I have never found much difference between LTE or 5G. I don't download massive files to my iPhone, where a faster data connection would make a difference.

It could be the case you're using on your iPhone however. If you have one (which you should), remove the case and test the signal strength without the case.

Thanks for your kind help,sharing valuable time!

In our country,unlimited recharge plan only limited to 5g and when network switches to LTE mode,automatically plan changes to 2 gb per day ! That’s the problem!
