This plan is provided by iD Mobile, which runs off the Three network. The plan is paid for monthly via direct debit. Most networks offer multi-sims, meaning the sim card you receive by post will fit your device. You can keep your existing number by informing the network at checkout or post-sale. The sim card will work with all unlocked mobile phones, make sure that your handset supports the iD Mobile network prior to completing your order. You should be able to cancel the sim plan within 14 days of the sale, should you not be satisfied with your purchase. To proceed with the order, simply click the ‘Get this Plan’ button and navigate to the iD Mobile website, where you can complete your purchase. SimOnlyPlans.com selects the lowest price plan offered by the network, which may mean a longer contract term (e.g. 12 months). For shorter term contracts you should generally be prepared to pay more than the advertised price at SimOnlyPlans.com.
