My new Galaxy S4 is not receiving calls or texts when I'm at home. I've tried turning on and off WiFi, restarting my phone which will bring in the messages I haven't received, but I haven't tried a factory reset yet.
Should I try a Factory Reset first and see if that solves anything? I honestly think it's a network issue and not a phone issue, but I don't know everything. ^^
Remove battery and sim replace
Do you have a cellular signal at home, and is wifi calling enabled?
DO NOT DO A FACTORY RESET
ANSWER BEARDAA QUESTION
We definitely want your services working! Some great questions have been asked already, how many bars of signal does your phone show? Is your WiFi calling enabled: Wi-Fi calling: Samsung Galaxy S 4? Does your phone work well for calls and text messages when you're in another location? Please let us know, and we'll get this figured out!
My wife and I have this exact same issue. We both bought our S4 at the same time and they were working great for about 2 weeks. My wife realized she was missing so many texts and phone calls. Our phones would work when we were away from home but when they are on wifi we miss the random texts. My wife had 20 missed texts in 12 hours. My wife took her phone to Tmobile store and called customer service. The store gave her a new sim and put her back on the network. That did not work, she called customer service and they did not have any good information to add. They had her factory reset, which did not work. She went back to the store for a new S4; which they wanted to give her a refurbished one after only 4 weeks of having the phone, she demanded the new phone, new sim. It worked for about a day and she was realizing she was missing messages and calls again. I thought mine was working also, but I too have been missing messages. We have been having to talk to people through Google Hangouts and facebook messanger because the S4 is not working. I had a S2 and she had an S3 with no problems at all working with the wifi enabled. We never once had to use the wifi calling unless there was no tmobile signal. We found a settings button in the advanced setting for wifi to automatically switch from wifi to network if the wifi is dropped. We clicked that and it helps when we leave the house, but not while we are at home because wifi is on and it's a log faster than the network.
Thank you for your help
I've had the same problem, with both a brand-new Galaxy S4 and with a T-Mobile G2X (LG P999). WiFi calling is disabled, but I'm connected to a WiFi network at home. The only oddity is that the cel signal strength meter shows only a single bar, when normally I get a solid 4 bars even indoors (and after restarting the phone the meter does show a solid 4 bars). It's almost like the phone's dropping off the cel network.
I am having this same issue as well. I fail to receive calls at times, I do not receive texts sometimes. When I restart my phone, everything floods in just fine, so I find myself restarting my phone 100 times a day in a paranoid way. I have called for support a few times, and have been walked through clearing data cache, doing a factory reset, removing my SIM card and verifying its information, was told to stop using Wi-Fi, especially when not at home so that the phone was not expending effort looking for signal (which made zero notable difference even on my battery life), nothing really has helped. I stopped bothering with tech support because I don't feel like spending an hour a day (or more) on the phone to fix a problem that is apparently built into the firmware, though I'm thinking this phone should have been at least $200 cheaper for all this hassle.
