What is BYOD and why is PiPcall a perfect BYOD solution?

BYOD (bring your own device) is an organisational policy that permits employees to use their own personal devices for work-related tasks.

PiPcall allows businesses to give their employees a business mobile phone service via a mobile app. The app comes with a mobile number, data, a calling and SMS plan. The app also offers advanced calling features unavailable on mobile phones like call recording and call transfer.

Employees benefit from having all business calls, contacts and messages separated from their private information and because there is no need to carry two mobile phones.

‍

When I call somebody from the app, what number will they be presented with?

Calls you make from app present the business number assigned to you. Your personal number is never presented.

‍

Can I use an existing business number?

Yes, we can organise to have all of your numbers ported to our system.

What choice of numbers do I have?

You can choose between:

Mobile numbers
Regional landline numbers
Non geographic numbers
International numbers
Freephone numbers

Get in touch with support@pipcall.com if you need a particular number you can not see in our portal.

Does the app use personal call plans?

As standard PiPcall technology requires a connecting local rate call to our telephony platform when an outbound call is made, this may use personal minutes, however if you enable Ring-me-back from the settings then our service will instead ring you to initiate the call.

The call itself, regardless of the destination is always charged back to the business and never the user.

Can my Data travel eSIM receive calls or text messages?

PiPcall’s Data for travel plans do not havea number associated to them, so they cannot receive calls or text messages.

Can I use iMessage / WhatsApp with an eSIM?

YES, if you have one of our data plans, you should be able to use iMessage on your iOS device without any problems. iMessage operates via the internet and a phone number is not actually required, you can use iMessage with just an iCloud email address to send messages.

Similarly, WhatsApp also works over the internet and a data plan will allow you to continue to access WhatsApp without any problems across the world.

Shared Number

Can I use one number in two phones? Or can I use one number on two phones?

Yes, you can use one number on two phones with Mobile+. The app becomes your business phone. Each app is assigned a dedicated business number. But you can programme your system to assign the same caller id to two business numbers, allowing one number in two phones. Outbound calls display the same number and a ring group is set up for inbound calls, so that they are picked up by both apps.

Can I have one number on two phones? Or can I have one phone number on two phones?

Yes. With Mobile+ you can have one number on two phones. The way the Mobile+ solution achieves this is with the Mobile+ mobile app.

Once a shared team number has been set up and a ring group configured, each person who wants to share the number will download the Mobile+ app onto their mobile phone. Every time they call out they will display the shared number and every time someone calls the number both phones ring simultaneously.

How does Mobile+ ensure compliance?

Mobile+ centralizes call records, making it easier to monitor and maintain compliance with regulatory requirements.
