Connection Problems: Is it the phone or the sim card's fault?
Alright, this is my first post over here in XDA, and I'm honestly don't know what forum to post on. Since this problem kinda started in my Galaxy Note 5, might as well take a shot in the dark and post it here! :p
Before, my Galaxy Note 5 Duos (N9208) was transmitting data back and forth flawlessly. One with 4G and another with H+ connectivity. Then, a few months ago, my phone's data suddenly became unusable! It suddenly froze up and I'm not capable of browsing the Web.
A few days passed, the data mostly came back to normal except for one key point. That is the fact that it can only access the internet when the icon beside the coverage is displaying "H+". Whenever it displays H, it won't work and it would be as if there's not Internet connection at all even when I'm in a place with full coverage. 4G is no different, the data came to a crawl to the point it would be plain unusable.
Thinking that something had gone terribly wrong, I sent my phone to the Samsung Service Center to check on the condition of the phone. They said it was fine, and the connections are all working fine. This got me thinking that my sim card(s) were the one at fault here. So I bought another sim card for my Note, and same result, the Internet of this sim also only connects at H+, not H nor 4G.
I then transferred one of my sim card to my spare Sony Xperia Z Ultra, which is itself not 4G capable so that's out of the question. But one of the symptoms from my Note 5 emerged, the Internet won't connect if it displays H, not H+. This made me think, is my phone infected with a virus and transferred itself to my new sim via sim infection?
TL;DR
- Galaxy Note 5 started having problems
- I sent Note for repairs but they said everything is OK
- I bought new simcard but still the same result
- I transfer one of the sim that was in my Note to my Z Ultra, same problems show up.
- I suspect a virus lurking on the cards
More information
- Currently using Note 5 ( N9208), Southeast Asia ( more specifically Malaysia) region.
- Providers are Maxis and DiGi.
- Spare phone is an C6833 Z Ultra
