There are three elements you should focus on while trying to find the best pay as you go SIM card.
• The first is the relevance of the SIM. You may have an old phone, a 3G compatible phone or one that is compatible with 4G LTE. You will need to pick the SIM card accordingly. You can get a 3G SIM that is backwards compatible. You can get a 4G LTE SIM that works on 3G and will move to 2G data depending on the network reception. But you cannot use a 4G LTE SIM in a phone that is not compatible.
• The second element is the size of the SIM. The more advanced the phone, the smaller your SIM should be. You may need a standard SIM, micro SIM or nano SIM depending on the phone you have.
• The third element is the network. Do not look for the best pay as you go SIM card based on the cost of the SIM or if it is free, unless you are sure of the network. You also need to check the charges.
