The next is an important one i.e “APN” you’ll get this from your GSM service provider or search it over the internet.
One more important step is to set APN type as “default”. Select APN type and type default as shown above. My data was not working initially. It started working only after I set the APN type to default.
Again long press the “Recent Apps” key and select “Save” to create this new APN.
The newly created access point name is added to the list. Select it so that it gets highlighted.
Now go 2 steps back to “IOT Hidden Menu” page.
Open “System Selection” and click on “Network Mode”
Select “GSM/WCDMA auto” to change the network mode from CDMA to GSM. You can again change to CDMA later via Settings.
After this, you should get GSM network signal with data if “Data” is turned on. If not, do one more step i.e changing “Network mode” to Automatic or GSM/UMTS as shown below.
To change “Network Mode” open Settings.
Select Network Tab(If in Tab View) and click on More<Mobile Networks<Network Mode as shown above.
Set the “Network Mode” to “Automatic” this way you don’t have to change network mode if you switch to CDMA network in future. You can also keep it as GSM/UMTS if you wish to use it on GSM network only.
By doing the above steps we’ve done two more significant changes as listed below –
Enabling Wifi Tethering – In the first screenshot above you’ll notice there is no “Tethering” option under “Connectivity”. It gets visible when we change the “Operation Mode” from “Production Network” to “Lab Network”.
Disabling Hands Free Activation – “Lab Network” mode also disables the annoying “Hands free Activation” pop up which keeps on bothering if your phone remains unactivated.
