Restarting your phone is one of the simplest and most proven ways to re-establish the connection to the network and ensure your data, SMS and calling service is working.
Some of the factors that may affect registering on the network are the following:
- The sim or chip has not been placed correctly.
- The sim is damaged.
- The sim is not active.
Here are some steps that will help to ensure you have correctly placed the sim into your cell phone:
Step 1. Based on the device, confirm which type of sim card is supported.
The three common types of sim cards are Normal, Micro and Nano.
Step 2. Verify the location of the sim card tray and match the position of the sim card in relation to the sim marker as seen below:
Step 3. Ensure the sim card is not damaged.
If the surface or gold foil of the sim card is scratched, or the sim is bent or broken, this can hinder the phone's ability to read the sim card and therefore connect to the network.
Here are a few examples of errors you may observe with a faulty or damaged sim card:
In the event of a damaged sim card, a sim replacement is recommended. This ensures you keep your phone number as it is transferred to a working sim card. Visit a store to get this completed.
Step 4. Ensure that you have an active data plan to be able to use the LTE service.
