Re: Mobile data and wifi issues - All Carriers

Perfect fix. At this time is speed is awesome.  Sprint's fix was to set phone to CDMA (3G)  Thanks again for the fix

I preordered a S10 plus through Sprint and received it on March 6th. The first week of it was fantastic. The last 2 days have been horrible. I started experiencing mobile data connection issues. Basically as if I was in a bad spot with no reception. I would get this notification, "Unable to establish a wireless data connection" all day, throughout various times of the day and pretty frequent at that. I would drop down to 3G or no service at all. That made daily use a pain not having apps load properly or fully.

 

Today, March 17th, I chatted with Sprint online chat support and have done everything from updating PRL, profile, and making sure all the current updates were done. Sprint tech support even did some stuff on their end to try and help my situation, but I was told everything checked out on their end and no outages in my area that should affect my mobile data connections/service. Then at the end of the chat, I was told that it's a common issue at the moment with the S10's and that Samsung is aware and an update should be rolling out, so I just have to deal with it for the time being.

Is anyone else who has a S10 having mobile data connection issues?

@Vong It would be better to visit Corporate Store for the technical support can physically look at the problem because this has something to do with CDMA and sprint network. They have to troubleshoot the phone physically. 

 

They have to check:

Mobile Data On

Network mode

APN settings

IMEI/MEID

Sim Card

@RedDragon i did go to a corporate store. Since i was the first to report this issue at that specific location, they almost didnt believe me. A Samsung certified tech checked all that and still had the issue at the store. I ended up switching to a new device and still had a few problems yesterday and today. I turned off band 25 and 41 a couple of hours ago as recommended by a few posts. Ive lost connection once after that. So we'll see how it goes.

@Vong Never turn off any LTE bands this will cause a lot of issues and never try to manipulate any settings under service mode this will cause a lot of issues associated with it. Seems like Sprint is having issue on their network maybe they are updating the network. if you haven't done already try to Reset network Setting this will erase any bluetooth and wifi and mobile data stored in your system

@RedDragon I have reset network settings. The problems happen less, but still happen. But even when I get back into service, its just slow. I'll bare with it and hope it gets resolved quickly as more and more people are experiencing these problems.

Have they tried a second SIM card? Have you tried the current SIM card in a new phone? Any change if the phone is in safe mode? Have you tried wiping the cache partition on your device?

Tried downloading Android messenger and still cannot send mms over wifi to an iPhone user for example. Rich chat messages between both of my s10s works fine though.

@SamsungAdam, They did not offer to try a different sim card while I was at the store, and it did not cross my mind at the time. The store I was at really didn't do much in terms of trying to help me with the issue.. One technician there told me I had it in "Automatic" mode for the Network mode and that was my problem because it needs to be in "LTE/CDMA." I told him from the day I received the phone, 3-6-19, up until 3-14-19, it worked flawless in "Automatic" mode. Mind you I was not even aware it was in "Automatic" mode and not "LTE" because it worked just fine up until then. He switched it to "LTE/CDMA" and basically left it at that. While I was talking to get my phone switched, I lost service in "LTE/CDMA" mode at the store. I insisted I switch to a new device whether it fixes it or not since I was within my 14 day exchange period. I didn't want to take a chance to leave with the original pre-ordered phone and have that issue outside of my 14 day period and then have a hard time swapping it should turn out to be a device problem. So they agreed to swap my pre-ordered device for one they had in-store. Still encountered the problem on my way home from the store with the new device.. At this point, I have reset network, updated prl, profile, cleared cache, etc. I do not have another device to try my current sim card in another phone. They did not swap sim cards from my preorder device to the one I received from their in-store stock. I also did not switch the sim card from my previous device, Note 8, to the S10+ as I didn't feel I needed to since it came with one and worked well right out of the box, at the time.

I've had the same exact issues. Got my S10+ on the 6th.. worked great till last Thursday night. Started getting offline and no connection errors like crazy. Samsung Support has been awesome attempting to help me out through Twitter DM and also following up with me. Sprint's phone rep seemed like she just wanted to get me off the phone. Sprint Care on Twitter DM wanted to have a tech specialist call me earlier but I decided to forfeit a little over an hour of my overtime at work to go to a Sprint store after they opened. They however would not allow me to get a new device. They got an email from corporate instructing them to not do this as the issue is software related and there will be an update eventually. I even brought up how hot my phone has been getting and my battery is draining super fast that it concerned me.. but just told me it was because of the phone constantly trying to establish mobile data connection. I don't know if the 6th is considered the 1st day in the 14 day return period or if I would still have tomorrow to goto a different sprint and complain.
