to make improvements right from their own mobile devices:
Change your current (3G) SIM card to a “4G” SIM Card
Subscriber Identity Module (SIM) cards are usually backwards compatible. Also, mobile phones are backwards compatible. So, it is important to note that issues raised by consumers who are complaining about bad Quality of Service may not be unconnected with the fact that they have not upgraded their SIM appropriately. Currently, 4G services are ubiquitous and it is important that consumers upgrade their 2G or 3G SIM cards to 4G and, check the availability of 4G services on their mobile phones.
Upgrading Your Phone to 4G Capability
Consumers should check their Mobile Phones to verify that they can work on 4G networks. If you want to check and upgrade your phone to 4G, please swipe up on the home screen of your mobile phone, tap on the Settings icon, look for the Network and Internet option and tap on it. After which, you can tap on the Mobile Network menu and tap on the Advanced option. Finally, tap on the LTE or 4G selection for 4G access. If you do this successfully, it confirms that your mobile phone is 4G compliant and you can use a 4G SIM card on it. If not, you need to buy a 4G compliant phone and go through the process again.
Please note that the step-by-step process may be slightly different for different Original Equipment Manufacturers (OEM) / Original Equipment Designers (OED). Below are examples of common Operating Systems.
