Can I return my sticker?

you have contacted support before removing the sticker from your SIM card.
How does the KnowRoaming sticker work?
The KnowRoaming Sticker is an ultra-thin SIM card. When applied to your home SIM card,
the KnowRoaming Sticker can detect when you are at home or abroad. When abroad, the KnowRoaming Sticker
takes over and switches you onto the KnowRoaming network, enabling you to connect to our local partner
networks worldwide. After returning home, the KnowRoaming Sticker switches you back to your home
mobile network and remains dormant. It’s not possible to be on both your home SIM and the
KnowRoaming SIM at the same time.
The KnowRoaming App is an account management tool. It allows you to add money to your account,
check rates, view your usage, purchase numbers and activate your service to receive your home
mobile calls abroad.
Is it difficult to apply the KnowRoaming sticker to my SIM card?
Not at all! Your KnowRoaming sticker will come with an applicator that is easy
to use and will correctly apply the smart sticker to your SIM card.
What if I experience issues abroad?
KnowRoaming Support is available 24 hours a day, 7 days a week. If you encounter any problems or
have any questions, contact our support team: email@example.com
Will the KnowRoaming sticker affect my home cell service?
No! The KnowRoaming sticker is dormant while in your home country. You are only switched onto the
KnowRoaming platform when you arrive abroad.
Can I transfer the sticker to another SIM card?
No, the KnowRoaming sticker will not work once removed from a SIM card. However, you can
transfer your same SIM card with the attached sticker to another phone.
Will KnowRoaming work on national only SIM cards?
Yes, KnowRoaming will work on a national only SIM card.
Will I receive my calls to my home mobile number?
KnowRoaming offers an optional service that allows you to receive all your calls to your home mobile number while using KnowRoaming abroad - connecting with friends and family back home will be as easy as if you haven't left!
If a forwarding number is available for your home country, you can subscribe to this service. If you are based outside of the U.S. and U.K. there is a monthly fee to activate this service. You can unsubscribe at any time - so there are no long-term commitments. The fee for this optional service is between $3 and $10 per month, depending on your home country. To enable this service, you will need to ensure that you have a call forwarding plan with your home mobile provider prior to travel.
Will I receive my text messages to my home mobile number?
We currently do not offer text message forwarding. While traveling abroad with KnowRoaming, you will not be able to
receive text messages sent to your home mobile number. When using KnowRoaming abroad, you can send and receive text messages
with your KnowRoaming numbers.
Which countries can I purchase a local/forwarding number for?
- Czech Republic
- Dominican Republic
- El Salvador
- Hong Kong
- New Zealand
- Puerto Rico
- South Africa
- United Kingdom
- United States
What is call back?
Call back is a calling system that reduces voice calls when traveling. The user makes a call
as normal but instead of the call being an outgoing call the call is disconnected when attempted
and the user receives an incoming call connecting the user to the desired number. In most destinations
customers can use either normal calling or call back.
What is call through?
This is a normal outgoing call. This is available in most destinations.
How long do I keep a purchased number for?
After purchasing a number, it's available for a minimum of one month. After one month, the number
will auto-renew every month until you unsubscribe from the number through the KnowRoaming App.
You can unsubscribe from a purchased number at any time.
Do I need to purchase a foreign number in a country I travel to?
No, you do not need to purchase additional numbers. You will still be able to receive and make calls.
KnowRoaming gives each account a US & UK number on which you can always be reached.
What happens if a local forwarding number is not available?
If a forwarding number is NOT available then you will not be able to receive your home cell calls abroad.
You will still be able to be reached on other purchased numbers as well as the free US & UK numbers associated
with your account.
What number shows up when I call someone abroad?
Your home cell number that you enter during registration shows up when making calls.
Can I get my voicemail while traveling?
Yes, KnowRoaming offers a voicemail service. It enables you to receive and check your voicemail as well as
record personal greetings. To access voicemail while connected to KnowRoaming, dial 605.
Will iMessage work while on the KnowRoaming platform?
Yes, iMessage will work but only with your email address.
Can I use KnowRoaming for data and my normal cell provider for voice and vice versa?
No, unfortunately you will only be able to access services from one provider at a time.
Can I check what the rates will cost before I use the service?
Definitely! You can check what the talk, text, and data rates will be on this website.
Alternatively, you can check the rates on our accompanying iPhone/ Android app -
there are no surprises.
