Can anybody with multiple service providers in the US test if the S10 can reconfigure for carrier branding out of the box?
Hi everyone,
Recently upgraded from my old Moto G6 to M31. Not sure why Samsung has not activated CA on this phone due to which we cannot get 4G+ (but only 4G) which can improve net speed by using multiple bands at once. Even the 2+ year old Moto G6 had this feature active.
Any way to activate that to improve network performance?

I don't know if there is much todo for it because Exynos modem can't modify. But maybe it support Carrier Aggregation but not with combinations used in your carrier and that's why you don't see 4G+ /LTE+ icon on statusbar or on *#0011# Service Mode.
I have made instructions to check Carrier Aggregation support from modem logs: https://mt-tech.fi/en/how-to-get-4g...ions-from-your-android-phone/#Samsung_Devices . If you can get modem log there can then see if there is anything about Carrier Aggregation. If it support i will then list it to cacombos.com site where can check Carrier Aggregation supported devices and supported combinations.
Exynos 9611 does support Career Aggregation 3CA, most bands are supported, but Samsung has chosen to keep it disabled, it can be activated by a secret service menu, but we need to find out the correct steps, codes, and sequence to access that menu, Samsung service engineers have these codes.
Bro head over to m31 guide and discussion of carrier aggregation and let us solve this problem

Hello everyone how can I remove a carrier lock on a Samsung Galaxy S5 SM-901F without asking the code from the Network Operator who lock the phone or from sites that provide the code for for a sum of money?
Hello,
Any idea how to carrier unlock the phone, besides calling the carrier? It is a work phone but I like to use my own SIM when traveling.
Pixel 4a 5G
Android 11
Build Number: RQ2A.210305.006
Carrier: ATT
I tried one of those "unlock" your phone service but was told that firmware cannot be unlocked.
It also seems to have an eSIM option but only if unlock and would be great to have two numbers on it.
I just bought Galaxy S20 FE 5G UW (SM-G781V) off eBay and it seems I have made a big mistake.
I am on Visible, which is MVNO owned by Verizon. I bought UW version just because I thought it would allow higher speed 5G.
Now I'm facing some issue.
Since this phone is Verizon specific phone, Verizon has customized firmware to force using their apps/services. The biggest thing I miss is Smart Calls. Verizon has removed Smart Calls and installed Call Filter app instead. This app does not even work if you are not on Verizon.
I read it may be possible to ODIN firmware with Spectrum or Comcast one to get it back. I downloaded CHA firmware, yet I do not see any difference. It still has Verizon splash screen and Verizon apps. Did I download wrong firmware? Could please direct me to right firmware if I downloaded wrong one?
I also read changing CSC code might work. However, Verizon has removed ability access *# codes. I found "Hidden Menu Enable Tool", but it does not even detect my phone.
How do I change CSC code on this phone?
