Tools to troubleshoot mobile network performance

Some good info from Gomo thread.

Just wondering how you know the active bands are N78+N1? Which phone and which app are you using?

Unfortunately for NetMointor free version on my Android phone, the app will only show the main N78 band even though it will show the bandwidth as 100 MHz + 20 MHz. The free version does not show the second active band.

BTW, SingTel 5G SA will usually show the bandwidth as 100 MHz + 20 MHz. StarHub/M1 5G SA will show the bandwidth as 100 MHz+25MHz as per NetMointor app. No real difference in terms of maximum 5G SA speed achieved based on my tests.

SingTel 5G NSA will usually show the bandwidth as LTE + 5G NSA, 20 +10 + 100 + 20 MH, or sometime 20 +100+20 MHz, as per the NetMointor app. Unfortunately the free version will only show one LTE band B3 in this case.

Net monster , network cell info
Android. Pixel 8 Pro on Android 16 QPR3 beta 2.1

Seeing the same on iPhone via *3001 menu

Thanks a lot.

NetMonster works for this purpose -- to see it is N1+N78 for 5G SA.

Network Cell Info Lite does not seem to have this functionality. Maybe it is worth to pay for the app as it is cheap.

NetMonitor non-free app is just too expensive (monthly payment).

My bad.. I paid for network cell info. As you mentioned it’s cheap.. Can offset using google opinion rewards.

it is doing n1 and n78 as aggregation. iPhone's field test mode does not show that properly. If use Mac to see, will see n1 and n78 connected at the same time

it is best if you have a rooted android phone (Pixels are very easy to root), and use NetworkSignalGuru (NSG) to see. It shows a lot of info. How many CA, what's the MIMO mode for each stream (2x2, 4x4)...

Interestingly NetMonster free version shows either M1 or StarHub 5G SA connection for my StarHub Prepaid S plan. In a way, it is not wrong either since both share the same 5G Infrastructure.

Network Cell Info paid version and NetMonitor free version seem to always shows the correct StarHub 5G SA connection.

Poco X7 Pro phone here.

Network Monster free version can also show 3CC (bandwidth shows 100 MHz +25MHz for StarHub Prepaid S 5G SA) or 2CC icon (bandwidth shows 100 MHz for StarHub Prepaid S 5G SA), not so sure how accurate it is though. By right I think it should not say 3CC but rather 2CC for the first case. And no CC for the second case.

When I disable 5G SA, it goes to 4G+ and shows 2CC icon (bandwidth shows 20 MHz +20MHz for StarHub Prepaid S 4G LTE-A). Then when it falls back to 4G LTE, 2CC icon will disappear and shows the frequency instead (1800 now, bandwidth shows 20 MHz for StarHub Prepaid S 4G LTE).

For my SingTel Prepaid 5G SA, it will often show 3CC (N78, 100+20 MHz bandwidth). Not so sure if this is correct. By right I think it should be 2CC only.

If I disable 5G SA, it will fall back to 5G NSA, and it may show up to 4CC (B3 + N78, 20+10+100+20 MHz bandwidth).
