Hello all
Have anyone faced an issue that G955N LTE signal unstable after upgraded?
I bought the Korean version in HK with CMHK carrier, when using stock AQDB firmware it went fine, after upgraded LTE signal always no data traffic almost every min., (sometimes signal dropped too and connect)
I also tried installing customs ROM and even flash to G9550 CSC but same.
Any solutions? or actually G955N 4G band is not suitable in this carrier?
Hi I have Samsung Galaxy S8+ model SM-G955U USC USA Model but I'm using it in Asia, so far all working well except it won't switch to Mobile Data once I'm away from the WiFi or I turn off the WiFi
Do anyone have a workaround for this?
Thanks in advance
Recently, I've started to have random issues with phone calls not coming through to my phone. I noticed that my primary SIM with LTE has noticeably worse service than my secondary SIM. Both SIMs are on the same network, but the issue appears to be LTE-related. Whichever SIM I use, once connected to LTE the service drops at least 2 bars lower.
This is a Singapore stock Dual SIM phone with Malaysian firmware (for more reguar updates). Do I need to update the modem firmware to be more compliant with Australia's networks? Or is this something inherent to the phone?
Thanks for any help!

I never used the Malaysian firmware but I can tell you that I've had the Russian one before and my lte signal was pretty bad in Canada. I've reflashed with the Saudi Arabian fw and I'm seeing significant improvements.

Thanks for the suggestion!
I'll have to give it a shot and see how it goes.
I have a Note 20 Ultra from Singapore that I am using on the Rogers network in Toronto. It's working great and I have signal but my data transfer speeds are sub par. If I flash the CSC for Rogers will I lose the ability to lose e-sim? Does anyone have any suggestions of what to do?
Thanks in advance,

If you mean changing the CSC, then you will. The phone will revert to stock. You may have to re-scan the QR code, (if that's how you got your eSIM activated), provided by Rogers to reactivate your eSIM or call Rogers..

You mean the N986B?
Sent from my BlackBerry Bold 9900
My N986B is from Singapore as well (CSC is MM1). I successfully flash Fido's Home_CSC (FMC) to it. It did not wipe my phone. I lost e-sim, only can use 2 physical sims for now. But I believe I can add them back by modify the CSC.
My volte and wificalling is still not working on Fido/Rogers network. Opened a ticket with Fido/Rogers asking them to add my imei to their database.

This is interesting - I thought the CSC was inextricably linked to a ROM for that region - in this case, North America, and therefore wouldn't work with a dual-SIM Exynos phone. Is that not the case?

Did you just flash the Fido CSC in Odin? If you're rooted there's a Magisk module to re-enable the e-sim, I'm just nervous to try it because I LOVE having e-sim and 1 physical + MicroSD.
Did you get better signal and speed after you flashed the Fido CSC? Will adding the IMEI to their database enable the VoLTE and WiFi calling again??
Thanks for your response!

Dual sim works after flash Fido's CSC. I tested with both Fido and Freedom sim in.

I flashed Fido's HOME_CSC through Odin after root. To my surprise, it worked. And it didn't wipe my phone.
I didn't notice any signal or speed changes. I just want to enable my VoLTE and WiFi Calling.
I insert my Fido sim card to an iPhone. Once VoLTE is working on the iPhone. I inserted the sim card back to my N986B/DS. Both VoLTE and WiFi Calling will work for about 10 minutes. Then stop working. So I know the VoLTE and WiFi Calling will working on my phone. I am still waiting Fido/Roger's 2nd level tech to call me back on the ticket.

Yes. IMS is registered on Fido's network. Both VoLTE and Wifi calling are working now.
Hi, I have yhe following issue and I need your thoughts please.
I have a Telus plan, canadian with US roaming option.
I am traveling in US alot. I have a Note 20 Ultra U1 from Samsung USA. When in US I can only register on Tmobile. Won't let me on ATT or Verizon.
With same sim card in Note20 Ultra "W" variant, canadian one, it wil register on all 3 major networks in US. No issues with the sim, I guess.
My provider said nothing to do with them, Samsung told me the same.
I reseted all network setings my APN is ok. VOLTE on. Only getting acces to Tmobile.
Any ideea how I can fix this ?
No ideas ? Might be the CSC ? Would XAC work ? Mine is XAA and also cannot get 5G in Canada with Telus on this device.
