Galaxy note 4 network problem

[hiren43]

I bought note 4 without bill from another guy which might be used for 1-2 weeks. While buying I jist checked imei and got to know that its genuine piece.

After using the phone, I came to know that I face signal problems from my carrier (Vodafone India). I changed the SIM several times to check if the problem peraist for another SIM. It did. The phone is working fantastic but only facing carrier signal problem as signals frequently drop to zero and when I use mobile signaled for internet, I'm able to google and open any website but with low speed even on 3g connection. With this, youtube is not able to play any video saying "no internet connection". However I'm not facing any wifi connection issue.

I'm having thought that If the phone was locked to a carrier and was unlocked and facing problems with new carrier? Can it be possible to see by IMEI if the phone was bough on contract?

It is made in Vietnam. [redacted]

Hiren43, I edited out your IMEI number. It's not a good idea to post such information on a public website. And, in this case, we wouldn't be able to get any specific phone information from the IMEI. Samsung has the annoying habbit of making many versions of the same device based on carrier or country. It would be more helpful if we had the exact model number (under the battery), the baseband and the build number (found in menu>settings>about phone)

Hey. Thanks for the reply.

I have attached the image of information you are looking for. I hope I could get the solution asap

Okay, the "H" variant of the Note 4 is for the Asia/Pacific market and does not seem to support 4g/LTE connections. According to the specs it supports 2.5G (EDGE, GSM/GPRS ) MHz:850, 900, 1800, 1900 and 3.5G (HSPA+, UMTS/WCDMA ) MHz:850, 900, 1900, 2100 . If your carrier uses other frequencies, you may be getting only 2G speeds for data, which would account for your poor performance. I don't really think there is much you can do.

But what about signal strength? Another SIM with same carrier is giving full signal on another phone. Is there anything that I can do.. Lile changing baseband version or something?
Sometimes I get "your network is not registered" message

The sim card is only the network identifier. It only provides information about the device account and doesn't change the radio. The "network not registered" is just telling you that it can't find the carrier signal which is probably a result of that particular model not supporting the frequency bands your carrier uses. This is purely a hardware issue, there's nothing you can do software-wise to change that. Sorry
