Sprint to fix an issue preventing iPhone users from connecting to LTE cellular data

Sprint message iPhone LTE issue

Sprint customers took to Reddit to complain about the inability to connect to Sprint’s LTE cellular data network after upgrading to Apple’s iOS 9.3 software update last week. The most recent iOS 9.3.1 update does not appear to have fixed the issue.

Sprint has acknowledged the issue in a text message to affected users and promised a fix, which will likely be delivered in the form of an over-the-air carrier settings update. “Your iPhone may be having data connection issues with the recent software update,” reads Sprint’s message. “We’re working quickly to fix. We apologize for the inconvenience”.

Affected users describe only being able to connect to Sprint’s 3G data network.

Restarting the device, restoring it to factory settings or reinstalling iOS from scratch does not help it re-connect to Sprint’s 4G LTE cellular data network. These connectivity issues force customers to use Sprint’s slower 3G network, which also causes the iPhone to draw more power.

“I’m having data issues as well on my 6s Plus in the LA/OC market. Over the past three days I’ve been troubleshooting on my 80 mile round trip commute via Field Test and Speedtest,” wrote one user in California.

“I’ve figured out that data transfer is broken when connected to Clear B41. No problems on Sprint B41, B25 or EVDO. I’ve created a ticket with Sprint Care, and supposedly they have notified their network team. I’m awaiting a response”.

The issue is especially problematic for people who are completely unaware of it and have 4G enabled in cellular settings: these folks are unable to receive iMessages and use other apps that require network connectivity unless they’re on Wi-Fi, without even realizing it.

Some Reddit users suggest manually adjusting the device’s LTE band in Filed Test Mode will fix the connectivity problem, at least until Sprint delivers a permanent fix on the network level.

    I have sprint, and they are cool in all. I don’t have any dropped calls, but sometimes these LTE speeds are horrible. I was at my sisters house the other day pulling less than 3G my phone said 1x. Only
    Sometimes do I get those broadband speeds. Most I’ve ever seen on LTE was 41mbps DL

  • I don’t know who you people are that say it’s “fixed.” Sprint hasn’t fixed shit. I’ve been on 1x for over three weeks…and it’s getting worse every few days. At this point, I have ZERO data connectivity, a 70% text message success rate, no voicemail and a 40-50% average for phone calls in which I can hear more than 80% of what the caller is saying. Sprint doesn’t even qualify as a cellular provider. They’re nothing but thieves who STEAL $120/month from me and in return, I get ABSOLUTELY NOTHING. I’m paying for unlimited talk/text/data/everything and instead I get DICK. NADA. ZILCH. A big fat 1x. In the insanely rare even a webpage does load, my average wait time is approximately 13 minutes.
