Learn to configure and troubleshoot mobile data connection issues with your prepaid or postpaid 3G/4G SIM card on your /e/ phone.
- A phone running /e/OS inserted with an active 3G/4G SIM card and a data plan.
Generally, an active SIM card with a data plan works out of the box. Still, there are a couple of things that might go wrong. Let us focus on those rare issues one at a time.
1. Ensure that the SIM card’s is active with a valid data plan and check whether ‘Mobile data’ is OFF by any chance
If you bought a new SIM card for your /e/ phone, make sure it has been activated by your mobile carrier. The best way to check it is by making a successful voice call or by asking customer care directly. Upon affirmation, if you paid for a data plan online or immediately, it is best you try a reboot of your smartphone.
Also, make sure ‘Mobile data’ is active. In order to do so, you need to access quick settings tray by swiping down from your phone’s top.
Turn ON Mobile data from quick settings tray by tapping on the ‘Mobile data’ tile as shown in the image below. Upon activation it would show network access type or mode viz. LTE, CDMA, WCDMA, GSM etc. For example LTE in the image below.
If Mobile data tile shows ‘No Internet’ continue troubleshooting.
2. Enable ‘Roaming’ and set ‘Preferred network type’ to multiple modes
Open /e/OS Settings and navigate to Mobile network from Network & Internet settings to enable ‘Roaming’ as shown in the image below.
Roaming is enabled as seen in the image below:
Tap Advanced in Mobile network settings to set ‘Preferred network type’ as ‘LTE/TDSCDMA/CDMA/EvDo/GSM/WCDMA’.
Pro tip: Make sure ‘Automatically select network’ is enabled under Network in Mobile network’s Advanced settings as seen in the image below.
If you still face issues, please continue.
3. Reset APNs to default
In Advanced settings of Mobile network settings, scroll down to the last option Access point names and open it to access APNs list.
Tap on the top-right icon to select ‘Reset to default’.
It restores default APN settings and that should fix your mobile connection issues.
Always consult with your mobile carrier’s customer care or website forums for APN related help. If it does not restores itself. Customer care is technically able to transmit mobile data APN settings to you directly over the cellular network.
4. Smartphone’s SIM slot related issues
Some of the smartphones only offer 4G data connection on 1st SIM slot or primary SIM. Please ensure that you have inserted your 4G SIM card in the 1st or primary SIM slot only. It can fix all your issues with a 4G only mobile carrier.
5. Network coverage related issues
If you have your setup in the basement or in lowest floor of an area surrounded by sky-scrappers, you might not get a data connection owing to signal issues at all. Make sure you have tested the mobile data on an alternate device to rule out any range or coverage related issues. Try it out on a different flower or on terrace once.
6. Broken or bad cellular chip
If you have tried out everything and still cannot get a mobile data connection on your phone. The chances are you have a broken cellular chip on your smartphone. Contact /e/support or your phone’s service center immediately for a quick resolution.
