What is a “SIM Only” plan?

There are no further services included in a SIM-only plan. You can get by with just a SIM card and some data, minutes, and texts, rather than a phone or tablet. Choose the Pay Monthly or Pay As You Go option that works best for you. They provide Pay As You Go phone plans with data caps ranging from 1GB per month to Unlimited. With Pay Monthly, you have more options than ever before, as you can sign up for a 1, 12, or 24-month plan. There is also no initial investment required for Pay As You Go.

Why SIM Only?

SIM Only is an excellent option if you do not wish to upgrade your phone but are nearing the end of your existing contract. With Pay Monthly, you have more options than ever before, as you can sign up for a 1, 12, or 24-month plan. Plus, a plethora of data plan options, from 1 GB to Unlimited. There is also no initial investment required for Pay As You Go. To switch to Three while keeping your current number, just send a text message.

If I make the switch to SIM Only, can I keep the same phone number?

Yes, you can. It is simple to complete the task online, or even over text message. Just be sure you supply them with the PAC code from your prior service provider.

Is a SIM Only plan able to provide me with 5G coverage?

Yes, as long as you are using a 5G smartphone and you are in a 5G coverage area, you will be able to use their SIMs without any problems.

Why choose Three?

When it comes to mobile plans, you want a provider that offers the best network, the easiest migration process, and unlimited data usage. That’s why Three stands out from the rest. One of their biggest perks is their 5G network access, available to all customers at no additional cost. And if you’re worried about the hassle of changing your number, Three has made it simple – just send a text to switch over. But perhaps the most impressive feature of Three’s plans is their unlimited data, with no speed limits or data caps to hinder your streaming, browsing, or sharing. Choose Three for a mobile experience that goes above and beyond.
