how to fix mobile data not working check if you have any signal bars on
your phone or not in case you do not have any signal bars the first thing you
can try is going into your phone settings SIM cards and mobile networks
and then selecting your SIM card if it's there
and going for preferred network type so in this case I have preference for 3G
networks and some of the phones you might have an auto option as well so you
can try one of these options if that does not work and you do not get any
kind of signal just go back to your home screen and in your phone dialer enter
*#*#4636#*#* now that will take
you to a testing screen and select phone information one if you only have one SIM
card base phone if you have dual SIM then you'll have two options and you
will have to choose accordingly in which slot you place your SIM card so in my
case I am on slot one and you'll have an advanced option here to select the
preferred network type in your case you might just go ahead and try a number of
options but the one I recommend is just to go with global Auto PRL and the phone
will itself try to figure out which network it needs to connect to once you're
done with that you can actually run a ping test to see if data works or not
in case you do not get any kind of signal still what you'll need to do is
you'll need to see if the SIM card is placed properly in your SIM card tray or
not and you can get like a tray opener and just open it up and see for yourself
if the SIM is even there or not so I do have the same properly placed
and you can make sure that it's placed correctly and just push it back in and
see if you get signal or not on your phone so in my case no bars and now I
have two bars and everything looks good now in case you do not get any signal in
some cases what you'll need to do is try the other SIM card slot because in
some of the older phones they have only 3G compatibility on one SIM card tray
and the other one is actually 4G so what you will do is you will take out your
SIM card slot and place it out in the other tray now all phones do not have
this dual SIM card option sometimes it's only for the SD card however this phone
that I'm demonstrating with is a dual SIM card phone and now I have signal
again on this phone perfect once you have the signal you're good to go
in case you do not have any kind of signal still one of the reasons why that
happens is because you have an incompatible SIM card and to determine
that what you can do is you can actually go into your browser if you have Wi-Fi
or you can go onto your computer and search for GSMARENA and then your
phone name so in my case my phone is called GSMARENA MI8 and then I can go
into the specification and see what bands my phone can connect to and then I
can actually contact the phone provider ask them what bands they support as well
and that will give me an idea if my phone will actually work on their
network or not the other thing is maybe they have like a different SIM card that
they need to provide to you so you can check that with them and they will be
happy to help you if you have got the signal working now the next step would
be to check if you have the data enabled or not so in my case I don't have the
data option enabled and once I enable it I should be having mobile data if that
doesn't help you and you had that option enabled but still you are not able to
get data what you'll need to do is you'll need to go into settings and you
can check if the VPN is turned on or off now usually the VPN is turned to off in
rare scenarios like office setting you might need to have VPN but usually you
can just turn it off and in case it's off still data not working we can go
back and the VPN option is sometimes not available on certain phones just for
a note you'll go in simcards and mobile networks then you'll select the SIM
card and then we'll check if there are any access point name configurations
here now you can actually search on Google a working access point name
configuration so in my case I have a service provider public mobile so it's
just search for them and then I got the configuration details that I can use for
Internet connectivity in case you find it too complex to figure out you can
always give a call to your service provider to send
the APN details and that will make it easy for you in case that helps you get
connected you're good to go in case that still doesn't work and you
still have the problem of no mobile data you can check if you have an option
called dual 4G and you can try to turn it on and see if it actually works or
not in case it still doesn't work there is
default setting option and in case you have a dual SIM phone you'll have to
actually select which SIM card tray you want to use for data now if you still
have the problem a common reason is because you have data roaming option and
in that you have set it to never sometimes providers use other networks
especially when you're in different areas and that can cause issue with
connectivity so you can just set it to always if you get charged then maybe for
exceptions only and that might help you resolve your data issue if you still
have the problem what you can do is you can go into your SIM card settings and
then check if you have mobile network connectivity enabled or not to automatic
if you still have the problem what you can actually do is sometimes the issue
is because people have a data plan setting enabled on their phones and what
that causes is it actually disables data so when I go into data usage warning it
says warned and turn off mobile data so sometimes it actually this
data because you have been over your limit and that causes it to stop working
so you can remove the daily data usage limit and see if your data works or not
so in rare cases the issue might be that you're connected to the internet however
there is some kind of DNS issue and to resolve that what you can do is you can
install the DNS changer app which is available on the Play Store and you can
select a specific DNS provider and just click on start using the app and it will
get you connected and working now if none of these suggestions work you can
try two things you can contact your ISP for your phone network and check with
them if they have enabled data for your sim card or not the second thing would
be that you can borrow a SIM card from someone and see if if you put that sim
card in your phone the data is enabled or not because that might help you
isolate the issue if especially if the data is working on their phone with
their SIM card I hope you find this video very useful and let me know if you
have any questions through comments and I'll be very happy to help you out
thank you BYE
