J7 Can’t Make Calls When Connected To Wi-Fi

Problem: Hello; I have a Samsung J7 and the issue that I’m having is that the phone connects successfully to Wifi and it does receive internet connection just fine. Trouble is that once it is connected to wifi, unfortunately it doesn’t receive any calls (regular calls, not through wifi calling). I have browsed through your already solved issues but fail to see a resolution to the situation. Any insight or help is greatly appreciated, thanks in advance!

Solution: If you have the Wi-Fi calling setting in your phone turned on then I suggest that you try turning it off first.

  • Turn on Wi-Fi.
  • From the Home screen, tap the Apps icon.
  • Tap Settings then Connections.
  • If necessary, slide the Wi-Fi Switch right to the ON position.
  • Tap More connection settings.
  • Tap Wi-Fi Calling.
  • Make sure that the Wi-Fi Switch is in the OFF position.

In case the issue still occurs then proceed with a factory reset. Make sure to backup your phone data before doing the reset. Once the reset is complete do not install any apps in your phone just yet. Try to check first if the issue still occurs.

If the above steps fail to fix the problem then you will need to contact your carrier regarding this matter as it looks like your calls are being routed using the mobile data network and since this mobile data is off whenever the Wi-Fi is used then you won’t be able to make or receive  calls.

J7 No Network

Problem: Hi Android Guy! I just bought a Samsung Galaxy J7 from Amazon and after two weeks of use, last night my network features shut off. I tried resetting my phone and shutting it all the way off, and I also tried removing my sim card (I have a cricket card and an unlocked handset) and nothing worked. It registered that my sim card was in, but could not send texts or calls. I factory reset my phone and it is working now, but I want to know if I should consider returning the phone for another. Is this an issue that you commonly see? If so, what might some solutions be that don’t involve factory resets?

Solution: If the factory reset that you performed fixed the problem then this might just be caused by a software glitch. Just use your phone as you normally would then check if the problem still occurs. If it does then you should consider having it replaced with another unit.

J7 Randomly Making Calls

Problem: I’m in Jamaica, using a Samsung galaxy j7 . I have a Digicel sim card and a Flow sim card (Digicel and Flow are mobile carriers). I got my postpaid phone bill and it shows that the Digicel sim has been making calls to the Flow sim. The calls are up to a minute long. Both of them are in the same phone so how can one sim be calling the other? I called Digicel and they said the charges are correct and the calls were made but how can that be? I’m not seeing any of the 6 calls in my phone’s contact history. I tried to replicate it myself by using the Digi sim to call the Flow sim and that’s the only time I saw it in my phone’s contact history. Is this an error on the carrier’s end or can the phone do that?

Solution: Your phone should not make calls on its own unless some app you downloaded is causing this to happen. What you will want to do right now is to backup your phone data then do a factory reset. Do not install any apps in your phone after the reset. Use your phone as you normally would until the next bill arrives. If it is still indicating that calls are being made to your other SIM card then this might be a carrier error issue.
