Before discussing about 4G LTE (1800MHz – Band 3) on Idea Cellular’s network, lets check what’s the maximum speed* the telco is able to deliver in ideal conditions* or what I could experience.

Idea 3G speed
Experience :
Spectrum Information
Andhra Pradesh Circle : 5 MHz of contiguous 1800 MHz spectrum + 1 MHz additional top-up spectrum = 6 MHz.
Karnataka Circle : 5 MHz of contiguous 1800 MHz spectrum + 1 MHz additional top-up spectrum = 6 MHz
Upgrading to a 4G SIM is free
Step 1: Visit any Idea Cellular showroom for upgrading from a 3G SIM to a 4G SIM.
Step 2: After taking note of your name, contact and an alternative contact number, you will be given a 4G SIM Kit (3-in-1, Normal/Micro/Nano) as per your SIM type – own network, MNP, NMNP, prepaid, or postpaid.

Step 3: You need to send ‘SIM <space> <New SIM 16 Digit Number>‘ to 12345, and you would receive a confirmation SMS within a few minutes.
Steps 4: As soon as the older SIM card gets deactivated, you can now use your 4G SIM.
Step 5: If you had registered for 4G in the pre-booking offer in your circle, you are entitled for 1GB of free 4G data to be used only on 4G network, which will be valid for 10 days.

Step 6: Your account will be activated with 4G services, and you’ll be able to latch on to the company’s LTE network, which will also be confirmed through an SMS.
So, it’s an ideal process of SIM Swap and your device would be able to latch onto LTE network within few minutes.
Idea 4G Speed Experience:
*These tests are done using the popular SpeedTest app with servers in Bangalore. Ideally, in normal day-to-day scenarios, one doesn’t generally select and pick up servers as different services use different servers located across various places across the globe.
