Alternative to WhatsApp I can put on DD's tablet?

[needaMNnamegenerator]

7yo DD is going to stay with my mum for a week, a much-needed break for both her and her brother!

She's excited about it but has asked if I can put Whatsapp on her tablet so she can chat with me if she misses me.

I can't as (age limits aside) Whatsapp has to be tied to a phone.

Is there something else we could download for DD to her tablet, that she could use to communicate with me while she's away?

(She's pretty tech-savvy FWIW).

Cheers :)

Facebook messenger. I think you can have it without Facebook.

Skype has a message function

We use telegram as a family but not sure if it needs to be tied to a number.

If it's an iPad and you have an iPhone, you can use iMessage.

If Android, Google Hangouts (don't know much about this one)?

My dc use Skype.

Thanks for the suggestions everyone :)

She's got a gmail account already so we're trying Google Hangouts first, seems to be working OK so far...

Try Cluster app. Uses email and is on playstore free.

I think there's email and phone option, so you can choose.

We always used hangouts when DS had an ipod touch rather than a phone

Slack is free and really easy to use! You can log in using google credentials too.

I've not used it or checked it out but there is Messenger Kids which some parents seem to recommend.
There are also other child friendly messenger apps.

We use Google hangouts. Can message and video call on it.

[Ditzyduck]

There's Kik where you can use just a username.

(Facebook) Messenger Kids seems to be the safest and most child friendly messaging app

[LostInTheColonies]

Messenger Kids . It's tied to an adult's account, and the adult has to approve all new contacts. Includes silliness with filters and so on. DD (11) loves it.

Can't she just email you? If she has gmail set her up an email address.
