New solutions to cellular network problems at the exhibition

At the exhibition "Communication" Innovative solutions in the field of communications are presented to the attention of visitors. The introduction of these and information technologies will allow you to more effectively deal with any problems in the operation of cellular networks.

Step 4. Restart your iPhone and check the network.

If you have Wi-Fi access, you can avoid manual setting time. In the subsection "Date and time" there is a slider "Automatically". After activating it, the iPhone independently determines the time in the set time zone - but only if the gadget is connected to the Internet.

Your obedient servant prefers not to use the automatic time setting, because his iPhone “counts” an hour more than it should.

Problems with cellular operator settings

After flashing iOS or replacing the SIM card, it happens that the iPhone writes "no network". In place of the operator's logo is the inscription "No network".

Often, users carry the device to a service center, where they try to return the connection for an additional fee, although in most situations the problem when the network on the iPhone disappeared can be solved on your own.

What to do if there is no access point to a wireless network nearby?

In this case, the most simple solution will create a Wi-Fi network using another iPhone, which can connect to the mobile Internet and distribute the wireless network. To do this is quite simple:

After these manipulations, a new item will appear in the main settings menu - Modem mode. After activating it, the device will begin to "distribute" the Internet.

Hello everyone! Mistakes are always annoying. And unusual mistakes are doubly unpleasant. Tell me, is it clear what the appearance of the inscription “PDP Authentication Error” means immediately after installation SIM cards on iPhone or iPad? Some kind of continuous set of words - PDP, authentication ... Apple, that's enough, stop there already! :)

When I first encountered this problem, I was very puzzled. The SIM card is new and just bought, the iPad also functions as it should - but when you combine these two variables, you get a "PDP authentication error" and no mobile internet of any kind. Fortunately, all this can be fixed on your own and without a visit. service center. How? Now I'll tell you everything, let's go!

So what do we see in iPhone screen or iPad besides PDP error? That's right, the inscription "failed to activate the cellular network." And this means that there can be three reasons for all this disgrace:

1. iOS settings.
2. SIM card.
3. "Iron" breakdowns.

We will not consider hardware, since hardware problems have slightly different signs - complete absence networks (and not just the Internet), other fault text, etc.

Let's take a closer look at the first two points. So, what can be done to resolve the "PDP authentication error":

As you can see, there are plenty of ways and there is nothing difficult - it is worth trying to do absolutely everything.

I want to stop at last version solutions, since in my case this was the reason for the authentication failure. It would seem that nothing complicated - go and change the sim. But it was not there…

So, we insert a new SIM card into the iPad - we get a failure. We insert it into the iPhone - it works. We install another SIM in the iPad - everything works. Conclusion? Bad card. We go to the salon - we change. We insert it again - again an error.

In general, in order not to tell you all my adventures, I will immediately move on to the result:

The PDP error disappeared after 3 (!) replacements of the SIM card.

Like this interesting story. Fortunately, a cell phone store is nearby :)

After all this, I concluded for myself - when buying a SIM card, immediately check its performance (preferably before paying). Because replacing the card, although free, is still not a very exciting procedure. And if you apply for this service several times a day, it becomes quite sad.

P.S. As always, I look forward to comments - tell us about your case, ask questions, advise alternative solution Problems. Write!
