Use your unlocked smartphone, just like you would at home. You won’t be charged to receive a call or text while you’re away.

Can I use this sim Data Only? - Of Course you can use the sim Data Only. Just set the APN and "Rock On"

We have now added the ability to pre purchase multiple months at the time of the initial order. We had a special request from Students at University of Chicago, Virginia Tech, University of North Carolina and VCU going to Europe for Fall Semester / Quarter Abroad.

It is important to note that while you are in Europe (outside the UK) and in the Go Roam around the world destinations, your max data usage per 30 days is 10GB. This means for example the students in the UK on an unlimited data plan will have 10GB data to use while on the continent. Of course the unlimited data resumes upon return to the UK.

A Tip To Rock Your Sim
You can add extra cash to your line to text non EU numbers or folks back home or we suggest you use an app such as Skype or iMessage or WhatsApp or Imo or Facebook Messenger. Take advantage of your massive data allowance to stay in touch.

When you arrive the UK or a "Go Roam" destination and first power on your phone, you will receive a welcome message from "Three" that will advise rates for local and international calls from that destination. These rates apply to direct dialed local and international calls and texts. These are calls outside of your included bundle.

Three Data is perfect for staying in touch with family while overseas. Your unlocked smartphone is capable of running a variety of video chat applications that are great for sharing such as Skype, Duo, Facetime and Whatsapp. Click here to learn about 6 video chat applications you can use to stay in touch.

What about other calls abroad – to local numbers for example?

Calls and texts to numbers outside of the EU, including local numbers in the place you are visiting, aren’t part of Go Roam and won’t come out of your allowance.
This is where you use the MRSIM WorldTalk feature included with the service. Simply dial our provided UK access number (UK - +442034146820), listen to the message and dial 00 + country code + number followed by # and the call will go through.
Thats Hot!
