Hi engelectrical85,


Thanks for reaching out in Apple Support Communities. I understand you're having trouble with notifications on your device and it seems to occur when switching from Wi-Fi to cellular data. I also see that restarting your device and removing then reinserting your SIM card will temporarily resolve the issue, but it returns. I know getting your notifications consistently is important; I'd like to help. It sounds like this might be primarily affecting third-party apps you have installed on your device. I'd recommend using the following resources to disable notifications for the affected apps, then restart your device and enable notifications again:



If the behavior continues, please reach out to Apple for additional support: Get Support



Best Regards.

Nothing happened, only notifications appear and come when I am on WiFi network only

but when I change it to LTE or 3G nothing appears or happened.


other side don’t see me online also for these applications Like Viber, messenger, WhatsApp, .... etc


LTE or 3G works well for internet speed

i try to change it to another carrier, it is the same issue

converting from WIFI to LTE this happened

only solution to reset the phone and remove the sim and add it back again to work getting notifications


I cant call apple support because I am at country not have support “Algeria” now

somthing not logic and many people now asking the same problem

i don’t know why and really I am going to sell that phone if not fixed soon


Any help please

Thanks for valuable feedback


1- I checked the carrier is already an approved partner for Apple

Algeria-Africa

but I found that have only 2 options

FaceTime, Hotspot

no LTE

is that can affect the notification issue ?

and what is the best case now for this carrier to be 3G voice and internet ?

and why the same SIM on android can get LTE normal ?

what do you advice ?


2- I called the carrier to check APN issue and they give me some data to put for internet and MMS but noting changed

what do you recommend ?


Thanks for your feedback and support

I found a solution as follow


1- if you will use sim internet please check first if your carrier supported by Apple cooperations or not

some counties not supported for LTE or 4G

if so please don’t use 4G LTE as it will make conflict on notifications and use 3G instead for internet and calls

try to reset your carrier APN setting from cellular option


2- in case of WiFi notifications not received it is a big issue from your internet provider

first download VPN application like VPN master from App Store

connect throw any another fast network, he will connect you automatic

it shall works well


3- Try to fix your WiFi to 5 ghz frequency and channel 11

you will find it under your WiFi router setting, advanced, WiFi, frequency and channel

it will give you fast internet speed and data and also prevent from toggle between 2.4 and 5

but take care as this frequency will affect signal strength throw walls


4- Update to last IOS version


5- Some people found a conflict throw iMessage and FaceTime

if you need to be sure just deactivate them as if as you can and see what will happened


Thanks and hope all be well
