Swytch uses your internet connection to work, so wherever you can, use a wifi connection to avoid using your data plan. Otherwise, a local data plan is the best option, as you will not get any roaming charges. If you are not planning on getting a local data plan when traveling abroad, please be extra careful with your data usage. Swytch does not consume a lot of data, but most of your phone activities will, and you could build up a massive bill with the roaming charges.

No, incoming calls are not charged.

No, the mobile operator will not charge you for Swytch's calls/texts. But since Swytch uses an internet connection to work, it will use the mobile data on your primary number if you are not using Wi-Fi for the internet.

Please write to our Customer Support.

We cannot stop ourselves from going on and on about why you should use Swytch, but here is the start.
By using Swytch number:
1. You save the cost of a second phone
2. You save the cost of the contract of a second (or third, fourth...) SIM number
3. If you are running a business on WhatsApp, you can have WhatsApp for personal and business separated on one single device
4. If you are an expat but have ties with the UK, then you can have a UK number using Swytch without getting a new SIM or paying extra for roaming charges.
5. If you are an online shopaholic, you can use the Swytch number to separate your communication about shopping from your other personal communications.
