How To Fix Wi-Fi or Mobile Data Connection Issues on Samsung Galaxy S4 [Part 1]

Problem #2: Mobile data doesn’t work and “Currently unable to download. Please try again later” error pops up after restarting the Samsung Galaxy S4

Hi there. I was wondering if you can help me. I cannot make calls or receive them. Messages cannot be sent and or received. Mobile data doesn’t work.

I’m on a plan and the bill has been paid. I called my phone company up and they told me everything is fine. “Currently unable to download. Please try again later” message pops up every time I start up Galaxy S4. I can only make calls and receive messages when I restart my phone, but only for a few minutes and then the connection disappears. When I try to make a call it doesn’t make the connection tone and when i try to hang up it freezes up and will not exit the call screen.

Any advice would be much appreciated. Cheers. — Bao

Solution: Hi Bao. Your issues–unable to make/receive calls, unable to send/receive text messages, mobile data not working — fall within the scope of your carrier’s technical support as they are all linked to their network. The only solution that we can suggest in this case is to do a factory reset. This basically resets the phone to its factory state, which means that all the basic functions like sending and receiving of text messages and sending and receiving of calls should be possible, provided you are linked to a working network. If a factory reset won’t resolve the issue, you have no other choice but to call your carrier and work closely with them again to identify the reason behind all these problems. Alternatively, you can also ask for a replacement unit to save you from the hassles of troubleshooting.
