[OFFICIAL] Singtel's GOMO discussion thread

[sad_xiaoxin]

Just checked my GOMO line on the iPhone. Same behavior today, it’s showing SA only, but it’s switching between n1 (20 MHz) and n78 (100 MHz).

Yesterday, it was still showing SA + NSA. Later, I’ll try setting my router to SA only to see if it loses internet.

Seems right. SA on ST is N78+N1 most of the time. There’s also N28 (700MHz) showing up occasionally.

How do you know it is switching between N1 and N78 under iPhone?

Most likely it is using Carrier Aggregation and use N1/N78 at the same time.

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.

I ran the code and opened the iPhone engineering menu that was shared earlier. Since the phone was idle, it wasn’t doing carrier aggregation, which wouldn’t makes sense because CA would drain the battery if it stayed active while idle. From what I understand, CA only kicks in during active downloads or uploads.

Unfortunately, the iPhone doesn’t really multitask in this way. I can’t, or don’t know how to, keep a background download running while keeping the engineering screen open.

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 netmonitor shows n77 on 5G SA but *#0011#* shows n78??

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)...

trust *#0011#. SG does not use n77

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

Just tried the GOMO SIM card on my 5G router.

Last week, when I fixed it to 5G SA only, it would disconnect and show no network.

PIC 1


Today, when I fixed it to 5G SA only, it worked. 5G SA now appears on the details page, three 5G SA bands are showing, and carrier aggregation is working too.

PIC 2 and 3

Out of topic though. Funny that you rooted but didn’t go further to remove ads.

I just wrote in to IMDA to ask on their position. To me, cutting off cellular service totally upon data exhaustion is not acceptable. Neither was there any transparency in the terms and conditions on this fact. I would consider cellular service a minimum essential service that any telco should maintain.

Just an update on this issue. IMDA responded and below is their response:

We refer to your feedback on 21 February 2026 regarding loss of cellular service while roaming in Japan with GOMO after exhausting your data allowance. Thank you for acknowledging the ADR advisory.

We would like to clarify that service providers have discretion in their daily operations, including making any provision on the functionality of mobile service while overseas. Note that roaming is enabled through commercial and technical arrangements between a home operator and foreign roaming partner(s). IMDA also does not prescribe how service providers should price, package and sell their services.

Neverthesless, we understand your concern about losing access to essential SMS services while roaming in Japan after your data allowance was exhausted, particularly for critical communications like banking OTPs and travel alerts.

We recognize the importance of maintaining connectivity for essential services, especially in the context of the 3G shutdown transition. IMDA will follow up with GOMO on the outcome and request them to contact you directly to address your concern regarding their roaming service implementation and the complete signal termination upon data exhaustion.

GOMO may contact you if more information is required or to update you on their findings and outcome. We appreciate you taking the time to share your experience with us. Thank you.

My GOMO eSIM is not used in a phone. I load it onto a special 5G device connected to my router so that it can function as a failover if/when the fibre broadband goes offline.

As such, I can link it to my computer and run commands to check on the connection details.

For the past few days, I rebooted the device but it's still on the LTE/5G NSA network.

Today I decided to remove the eSIM and reload it. I can confirm that once I did that, I now get a 5G SA connection.

Previously, I would see an LTE signal. Now it's purely 5G:

Band Information:
Radio Interface: '5gnr'
Active Band Class: 'nr5g-78'
Active Channel: '45216'

Band Information (Extended)
Radio Interface: '5gnr'
Active Band Class: 'nr5g-78'
Active Channel: '635040'

Bandwidth:
Radio Interface: '5gnr'
Bandwidth: '5gnr-100'

I'm on gomo 5G SA now. 5G SA has lower signal strength compared to 5G NSA hmm


Read HWZ Forum Rules!

 

[FatalethaL]

Just spoke to GOMO chat rep. He mentioned GOMO is still on NSA, not SA.

On the other hand, I found that I missed the SMS from GOMO to switch from 4G to 5G+ SIM card for free before 31 Jan 2026.


This got me thinking - 4G SIM card can use 5G NSA ah? All along I have been subscribed to 5G plan.

Anyways I got curious and requested new SIM (physical), and it showed $0 replacement cost/fee. Might as well! I applied and now waiting for collection.

Update:

• Received new physical SIM card on 26th Feb 2026 evening.
• The new SIM card is yellow in colour. Invoice printed, "GOMO HYBRID 5G SA HALF SIM".
• Old SIM card is blue in colour (when i first subscribe). The invoice printed "HYBRID SIM".
• Activated new SIM, reboot phone.
• At home while indoors, signal jumps between 5G NSA and 5G SA. Most of the time it is NSA.
• This morning head out to work. While outdoors above ground, it shows 5G SA.
• While commuting underground MRT and indoors, it shows 5G NSA. Right now sitting in office, it is showing 5G NSA.

I used nPerf and SIM Status to check NSA/SA status, and using Pixel 10 Pro XL.

For Android phone owners, this is how you check SIM status:

• Settings >> About phone >> Sim status

Running GOMO on my OP15
5G-SA is active with Vo5G

 

[Fellowes]

GOMO on S25 is using 5G SA and VoNR.

Nice, more ppl got the 5G-SA already
