3 UK Prepaid PAYG Phone SIM

Sale price AUD$9.00 Regular price AUD$94.00
 ✓  Express Shipping!
 ✓  Detailed Activation Guide!

IN STOCK - can roam to 71 'Feel at Home' countries

- No problem to activate outside UK

- Can extend out for further blocks of 30 days with credit sold by dataGO


Buy SIM preloaded with the add-on (+ a bit of extra credit for intl calls) 

The preloaded SIM is cheaper and easy to get up and going.
The option for extra credit allows top-ups, as the initial preloaded Add-On only lasts 30 days from the moment you first activate it (auto-activates the first time you put it in your phone and connects to network).

Buy blank SIM + credit PIN

Some people like to just buy the blank SIM (aud$9) and load it up with credit as required (turning some of the credit into an Add-On as they please).
As an example:
​-> receive SIM in mail and credit (say 25 pounds credit) via email
-> add the credit via 3UK online portal and buy 20 pound add-on 
-> leaves 5 pound left over for odd call/sms to non-uk number
-> can add more credit or buy another add-on for following month via credit PINs we sell here, and top-up via 3UK web portal here

IMPORTANT NOTE: If you add the credit (sits there as balance credit), and if you don't buy the 'Add-on', you will be charged at casual data roaming rates outside the UK - this will burn thru your credit.
Basically, make sure you use the credit PIN to buy the add-on if you want the free data roaming.

Why Buy?

1) Local SIM for low cost data & calls in the UK.

2) 'Feel at Home' free roaming in 60+ countries- in which you use data/call/text on your UK plan.

3) Buy with a PIN/credit for  'Calls/SMS/data pack' - ready to hit the ground running.

Avoid the hassle and buy a prepaid 3 UK Phone SIM from dataGO today!

If you are heading to the 3 UK Pay As You Go prepaid Phone SIM card gives you the best deal for data, calls and text you are likely to find!

It is also as good as deal as you are going to find anywhere for their ‘Feel at Home’ countries which include most of the EU and lots of other places around the world -see more detail here 

Feel at home roaming is a great value for money deal if you are going to any of these countries!

There are five add-ons that will enable 'Feel at home roaming'.

The 10 and 15 pound add-on give 1GB and 5GB of data that can also be used when roaming. The three bigger add-ons (20, 25, 35 pound add-ons) that have a fair use policy of maximum of 12GB when roaming (so really the 20 pound add-on is the best one):

£10 = 1GB, 300 min calls, 3000 SMS

£15 = 5GB, 300 min calls, 3000 SMS
£20* = 12GB, 300 min calls, 3000 SMS (12GB max data roaming)
£25* = 30GB, 300 min, 3000 SMS (12GB max data roaming)
£35* = All-you-can-eat Data, 300 min, 3000 SMS
*Fair use policy of 12GB data roaming applies to 20 pound add-on and up

3UK Phone SIM with preloaded Add-On
Just pop SIM in your phone and see it connect to the network (helpful sometimes to turn phone fully off/on) and away you go - your 30 days to use the Add-On starts from the moment of the first connection to the network. You can top-up/renew Add-On at the end of the month.

Blank Phone SIM + 10, 15, 20 or 25 pound PIN (PIN=top-up voucher)
This allows you to:
1) Activate the SIM > then add the credit PIN in the Three UK online portal
2) Use 10 or 20 pounds of their balance to purchase the 'add-on'

They then have free data roaming in the partner countries for the next 30 days, and have some pounds balance left over to use for international calls (calls to non-UK numbers not included in the 'Add-on').

Note: If you don't buy the 'Add-on' and only apply the credit, you will be charged at casual data roaming rates - this is not a good idea!
If you want free data, make sure you purchase the 'Add-on' with your credit, or get the preloaded SIM (easiest).
You can't use a non-UK credit card in the online portal - hence why the credit PINs are the easiest workaround - you can buy them here

Also, if you use data in 'Non Feel at Home' countries you will be charged at a casual rate, and it will burn through any balance on your SIM - again not a good idea - turn mobile data off in non-Feel at home countries, or use a dataGOroaming SIM if you require data

Need more than what is included in the plan?
1p = Data (MB)
2p = Text (SMS)
3p = Calls (min)
These are the rates for the UK.

See below for all other charges.


3UK Phone Pay As You Go plans now allow tethering. 

The minutes and texts included in Add-ons are for standard UK mobiles and UK landlines - not for calls and SMS to non-UK numbers (which requires extra credit), most people just use the free roaming data to Skype /Viber /iMessage instead though :-)

-       Calls: outgoing 24.5p /min (min charge 30 sec, after which per sec)
-       Calls: incoming 7.1p /min (per sec)

What about roaming in non- "Feel at Home" countries?
Make sure you are aware of the network partners and pricing here.
Note; on the pricing link above, enter country, then click the 'PAYG' tab (on the top right).

GETTING CREDIT can sell you credit in £10, £15, & £20 top-up/recharge vouchers here.
Credit once applied to your account does not expire.

You need a UK Credit Card to buy credit on the 3 UK website (hence why we sell top-up vouchers with the SIM + also via the above link).

You can also buy top-up vouchers from convenience stores in the UK.

3 UK has great coverage around the UK.

All 3UK SIMs are TRIO size now - the one SIM pops out to any size required.
See more SIM size info here

Express is a flat $6

If you run out of your allowances included in your add-on/plan or are using Pay As You Go credit, you'll be charged at roaming rates that are lower than normal. These rates are:

  • 20p per minute to make calls
  • 7p per text
  • 10p per MB

If you have a credit limit or zero spending cap, this will still apply while you're in a Feel At Home country.

Important Notes on ‘Feel at Home’
​It’s designed for trips away rather than living abroad, so if you use your device exclusively in a Feel At Home country for three months within a twelve month period, you won’t be able to use your device abroad anymore.​ More info on ‘Feel at Home’ here

It’s always free to receive calls in a Feel At Home country.

Convenient SIM option

Everything worked well. For a small cost it was great to have the SIM ready to go as we arrived in London.
