WorldSIM numbers are UK mobile numbers. Hence the international code +44 applies.

1. From most fixed lines dialling a WorldSIM number will be charged as a call to a mobile phone (BT landline: 12.5p/min peak, 4p/min off-peak).
2. As mobile networks may levy different charges, it is best to check with your service provider about their charges.
3. Although many mobile phone users have inclusive minutes with their existing network provider, some network providers may still charge you to call WorldSIM numbers. This decision is taken by each individual network provider to the exclusion of WorldSIM.
4. It is the responsibility of the network provider to play a recorded message to alert their customer that the number that their customer is dialling is a chargeable call.

If after checking with your network operator, you do find that calls to WorldSIM numbers are chargeable, then here are three easy ways to help you to overcome this:
1. WorldSIM to WorldSIM calls are only 10p per minute. For further information, please visit our Tariffs and Coverage page.
2. Register for free with https://www.cheaper-calls.com. Cheaper-Calls offer ultra-low international calling rates. Cheaper-Calls is a pin less dialling solution that enables you to make cheap international calls for less than 1p. The unique service saves you money by offering local numbers for each one of your international contacts. Cheaper-Calls to WorldSIM calls are only 12p per minute.
3. Add a virtual number to your SIM card, then its the cost of calling a local number. Find out more here: https://www.worldsim.com/virtual-phone-number Please remember that the WorldSIM sim card will only work in ‘unlocked’ handsets. Your network operator or a mobile phone repair shop can unlock your handset for you.

Once we have completed your request, the next time you make an outbound call, depending on your requirements, your number will either appear as withheld, or your Caller ID will appear as the US or UK number.

To find out whether your phone is 'network unlocked,' insert a SIM card from a different network into your phone. If it operates normally, it is unlocked. If not, you can ask your operator for an 'unlock code' which it is obliged to give you, though conditions and charges may apply.

Alternatively you can unlock it yourself by taking your phone to an independent phone shop or by trying one of the independent unlocking websites.

Porting Authorisation Code (PAC) is a unique identifier (normally 9 characters long and in the format "ABC123456") used by some mobile network operators to facilitate mobile number portability (MNP). This allows users to retain their mobile telephone number when switching operators.

WorldSIM numbers are non-transferrable neither to WorldSIM, nor from WorldSIM, nor within WorldSIM. If your WorldSIM is lost, stolen, or damaged, and a replacement sim is acquired by you, the replacement sim will arrive to you with a new number.

The reason for this is that WorldSIM offers a specialised international roaming service that works on a call back system using special numbers. These numbers are not part of the mobile number portability scheme. Due to this reason, we are unable to provide you with a PAC code.

As an alternative, you can set up call forwarding to and from your WorldSIM number. Network operator charges will apply.

WorldSIM is compatible with the majority of mobile phones purchased in the last four years. However your phone must be 'network unlocked' to use WorldSIM.

Japan and South Korea: WorldSIM works in Japan. To use WorldSIM in Japan requires a 3GSM (or 3G) mobile phone that supports WCDMA 2100. This is still a GSM phone. However it is using 3rd generation technology which is deployed in Japan. There are two different 3G standards presently in use. To ensure that you have the correct handset for roaming in Japan, it is advisable that you check with either your current network operator, or preferably refer to their handset’s handbook to determine whether or not it is WCDMA 2100 compatible.

Canada: WorldSIM works in Canada. To use WorldSIM in Canada and to register to the recommended Bell or Telus network provider, please be requested to use a 3G handset which supports 1900MHz band.

To retrieve your PIN/PUK code, please contact us using the Contact Us - Submit Enquiry Form and we will send the code to your registered email address.
Note that the PIN/PUK code cannot be changed to a more memorable number.

If your sim is not used or topped up for 12 months, the sim will automatically be deactivated after 12 months from last use, and the mobile number and any unused credit will be lost.  If this happens, you will need to purchase a new sim from our selection of global SIM cards.

Virtual Numbers refer to geographic landline numbers. These are numbers that start with an area code that is related to a specific location. For example, a number that is from London will start with +44(0)207. Users can dial this number at the cost of a local call and (if they are in the same country).
It is possible to have over 40 additional local numbers associated with your WorldSIM. Some countries require additional documentation to be supplied in order to set up a local number. This is a fraud prevention measure, and is required by regulation.
The cost of each number varies. The information page gives you an indication of how much each number costs per month. The longer you purchase a number for the cheaper it works out to per month. When you select the number in 'My Account' it will show you the total value of the purchase.

Outgoing call rates are exactly the same as making a regular call on your WorldSIM. To receive an incoming call on your Virtual number there is an additional charge of $0.15/min to your regular incoming call charges.

Yes. Once you have purchased a number and it shows in your account you can log in and change the Default Caller ID to any number you prefer. Then whenever you make an outgoing call the number you have selected will show. You can change Caller ID at any time.
Simply purchase a Virtual number which matches your country of residence. Then divert your existing mobile number to your virtual number (this would be the cost of calling a local number) and we forward all calls to your WorldSIM, so your contacts can continue to call your regular number whilst you travel the world. Please note, it is recommended to check with your mobile operator for any additional divert charges.
Numbers are usually assigned to your account/SIM instantly and can sometimes take up to 24 hours. Please allow this time to pass before you get in touch with us. There are some countries that require address proof. Please check your email in 24 hours after placing an order for a virtual number.
Yes, once a number appears in your account it is ready to use. You can start making and receiving calls at any time.
It is not possible to choose specific Virtual Numbers. Once your order has gone through a number will be generated and will show in your account. But you can choose for most numbers the area code.
If the expiry date passes and you have not renewed your number it will be unassigned. You can still purchase another number from the same country and city but you will be assigned a new number. We cannot retrieve lost numbers back to your account.
In order to stay in touch, you can forward all incoming calls from your WorldSIM to any number. For example, when you return from your travels you may want to forward all calls to your local mobile. To do this, simply click on the forward option next to your UK number and enter the number you wish to forward all calls to. To cancel the forward, uncheck the box and confirm. Check here to see all call forwarding rates.
Your Virtual number is valid till the period you had purchased the number. You can check the expiry of your number by going to My Number Section under your account.

Yes, it is chargeable to receive calls on your Virtual numbers. To receive a call on your Virtual number there is an additional charge that will vary depending on where you are.  Take a look at the chart on our tariffs page, click on 'incoming calls' and look at the rates for 'US & virtual numbers'.

No. Please note that virtual numbers are landline numbers and cannot receive text messages sent to them. You can only receive text messages to the UK number which is the default number of your SIM card.
For a few virtual numbers, there are a few countries, for which we require Address Proof in order to activate your Virtual number. All you just require is to respond the ticket after sending a Valid Address proof to [email protected] with the subject as the ticket number and the Customer Service would respond to you within 24 hours after activating your Virtual number.

When logging in to your WorldSIM account online, if you see an NP number in place of your WorldSIM phone number, dial *133# to retrieve and activate your UK number. This should resolve the issue.

If you have done this, yet your issue remains unresolved, we will do everything possible to give you the support that you need.

WorldSIM is compatible with the majority of mobile phones purchased in the last four years. However your phone must be 'network unlocked' to use WorldSIM.

Japan and South Korea: WorldSIM works in Japan. To use WorldSIM in Japan requires a 3GSM (or 3G) mobile phone that supports WCDMA 2100. This is still a GSM phone. However it is using 3rd generation technology which is deployed in Japan. There are two different 3G standards presently in use. To ensure that you have the correct handset for roaming in Japan, it is advisable that you check with either your current network operator, or preferably refer to their handset’s handbook to determine whether or not it is WCDMA 2100 compatible.

Canada: WorldSIM works in Canada. To use WorldSIM in Canada and to register to the recommended Bell or Telus network provider, please be requested to use a 3G handset which supports 1900MHz band.

If a Multi IMSI sim is not used or topped up for 3 months, the sim may automatically be deactivated any time after a minimum of 3 months from last use, and the mobile number and any unused credit will be lost.
This is a requirement from the operator from a regulatory perspective. If this does happen, we would be happy to offer you a free upgrade to our newest sim which comes packed with new features and benefits.

Please be advised that as numbers are not transferrable, the new sim would arrive to you with a new mobile phone number.
