Solutions for cellular data and Wi-Fi connection issues:

Solution 1: Update telephone operator data (cellular data)

Operator updates are much the best because they don't need to be powered off, and you can also do whatever you want while installing the update. But as you can hear, the updates are as they are i.e. they may contain bug fixes and they may fix your problem.

Check the updates available on your iPhone or iPad, go to "Settings" to find software updates from telephone operators. If there is one available you can download and install it, but if there is nothing please wait patiently..

Solution 2: Force iPhone to choose the best network tower (cellular data)

If refreshing your tower doesn't seem to fix the situation well, your iPhone running iOS 12 may not be connected to the best tower available. You can force your iPhone to connect to a better tower in your area. You force this connection directly on your iOS, or through a third-party app like Open Signal.

Solution 3: Remove and replace the SIM card (cellular data)

To really refresh cellular connectivity, you can eject your iPhone's SIM card. Without a SIM card, your iPhone running iOS 12 will not be able to connect to the cellular network. By removing and then replacing your SIM card in your iPhone, you are performing a kind of hard reset.

You can use any sharp object to pop the SIM card out of your iPhone, but we still recommend that you use a special SIM eject tool to avoid damaging the shell of your precious iPhone.

Solution 4: Forget current Wi-Fi (Wi-Fi) connections

If you think that maybe the problem is with improper handling of the Wi-Fi network connection, you can try to forget it in your iPhone. By “forgetting” a Wi-Fi network, your iPhone will erase this saved network. You can then start all over again with it.

Go to "Settings" → "Wi-Fi" → "i" which is next to the Wi-Fi network → "Forget this network" → "Forget". Then go back to the main menu of "Wi-Fi" and reconnect to the Wi-Fi network you deleted.

Solution 5: Turn Wi-Fi on and off (Wi-Fi)

The Wi-Fi Assistant automatically switches to cellular data when the Wi-Fi connection is weak. This tool is really great, but it can frustrate us when the mobile connection is not good. Try disabling and then re-enabling this feature to see if the situation improves, otherwise disable it altogether. You will find the On / Off button in “Settings” → “Cellular Data” → “Cellular Data”.

Solution 6: Change the DNS server (Wi-Fi)

The DNS server - or domain name system - scans website names into IP addresses that your iPhone connects to. You are probably using the default DNS server, which explains the slowdown.

You can try customizing the DNS server to speed things up. To find this option, go to “Settings” → “Wi-Fi” → “i” of current network → “Configure DNS” → “Manual” → “Add server”, then add the server you want. To use Google, type 8.8.8.8 or 8.8.4.4; to use OpenDNS, type 208.67.222.222 or 208.67.222.220. Then finish by pressing “Save”.

Solution 7: iOS software update (cellular data & Wi-Fi)

Just like the update for phone companies, it is really important that your iPhone is running the very latest version of iOS. It's okay to hesitate if you're still on an older model of iPhone, but if you're already using the new iPhone XS or iPhone XS Max that's already on iOS 12, install the very latest update. is imperative.

Always make sure to check that you have the latest iOS updates installed. You can regularly go to the settings or activate the automatic update.

Even if you are on an older model of iPhone, it is strongly recommended that you always install system updates to make sure you fix any bugs.

Solution 8: Turn airplane mode on and off (cellular data & Wi-Fi)

Another trick that always works to keep your network up-to-date is to turn "Airplane mode" on and off. You can do this from the Control Center by tapping on the icon containing an airplane. Remember to turn Wi-Fi off and back on at the same time. By doing this, you can be sure that the network connection is completely disabled for a while, allowing the iPhone to refresh this connection.

Solution 9: Reset network settings (cellular data & Wi-Fi)

Network settings also need to be reset from time to time. You might not really consider this fact, but your iPhone's network connection to local towers might be scrambled and need some sort of unblocking. Of course, you don't need to access the tower, you can do everything from your iPhone.

To do this, go to “Settings” → “General” → “Reset” → “Reset network settings”.

Solution 10: Force restart iPhone (cellular data & Wi-Fi)

It is indeed an all-powerful solution as one could say. Indeed, when the tweaks in the settings cannot solve anything, it is a good idea to restart the iPhone to refresh the entire device. Sometimes that's all that your iPhone, running iOS 12 or earlier, needs.
