Free SIM Cards: Frequently Asked Questions
If you are looking to change your mobile phone network, the first step is to send off for a free SIM card. This will allow you to begin the process of switching your existing mobile network over to a new provider. There are many “SIM-only” (month-to-month rolling contract) mobile operators available in the UK that provide better value and flexibility than those offering long-term contracts. SIM-only plans allow you to cancel at any point, switch networks easily, and change your plan whenever you see fit.
Why order a free SIM card?
Ordering a SIM card online is the easiest way to begin the process of changing your mobile network. Although you can buy SIM cards relatively cheaply in supermarkets and other stores, ordering online is an efficient and stress-free method. After delivery, you can place your SIM in your handset and begin using it immediately. However, if you wish to keep your existing telephone number, you will need to follow a few other steps first. We explain how to change mobile networks and keep your number in more detail below.
Will the SIM card work in my phone?
It is important to be aware that not all SIM cards function in every handset. If your phone is locked to a particular network (e.g. locked to O2), it will only work with SIM cards that use the O2 network, or networks that use O2’s infrastructure, such as Tesco Mobile. However, if your handset is not locked to any particular network (known as “unlocked”), it will be able to accept a SIM card from any network. Note: It is useful to check what size of SIM your handset accepts before ordering. The main sizes are standard-sized SIM, micro-SIM, and Nano-SIM. Most mobile networks offer all major SIM card size options.
What is the process to switch mobile networks?
To change networks, you first need to order a SIM card from the new network you wish to join. If you want to start afresh with a brand new number, you should be ready to go. Every SIM card comes with a new telephone number as standard. But if you want to keep your existing number, you need to obtain a Porting Authorisation Code (PAC Code) from your existing network. This code gives your new provider permission to move your number across. The process can take a couple of days to finalise. In most cases, the process is hassle-free.
What are the best SIM cards for international calls?
The vast majority of SIM-only networks offer competitively priced international calls. Having said that, Lycamobile is among the best providers for international calling. The network has very favourable dialling rates and roaming charges, plus specialist plans for travelling or calling particular areas of the world. People wishing to call India, China, Bangladesh, Australia, the U.S., and others should certainly consider Lycamobile.
What is the best value SIM-only deal?
It really depends on what you are looking for, but we think GiffGaff provides some of the best rates and network availability alongside helpful customer service. ASDA Mobile is great value for money but lacks the level of customer support of its rivals. But you can still find competitive deals with Tesco Mobile and O2. The Three network is also a great choice if you are a heavy data user and need the option of upgrading to an unlimited data allowance.
