is there anyway i can retrieve the pictures from my previous chat on whatsapp .
my phone was lost and now I have a new phone and have been able to retrieve the whatsapp contacts but could not retrive the pictures.
Hi Kuku, you can retrieve the pictures if you have a back-up
we are travelling on a cruise ship to france, spain italy and the UK and I would like to know can I use Whats app on my android phone without a special plan from TelU for texting messages to back home in BC . Do i need a wireless connection to use whats app and what charges would i face to use this service.
Hey, Pat, you can use WhatsApp with a wireless connection. You may not incur any charges. However, please ensure that your wireless connection is free or with an unlimited plan. Hope this helps.
If i use whats app abroad and i use it to text or phone i understand this is free if i am using the wifi. However if the person i am texting opens the text and is not in a wifi area does this use their mobile data or will they not be able to see the text until they are in a wireless area. In other words is there any chance of me being charged for sending or receiving a text message or tel call using whats app??
If they have a internetconnection (wifi/3G/4G) they can read the message, otherwise they wil get it when they have a connection
So, if I understand correctly, the person sending or receiving can only see the message if they are on wifi. What about phone calls? are they always free like skype or is there a charge if the person call happens to be in a nonwifi environment.
The person needs a internetconnection. WiFi OR 4g etc
Will text messages sent from a different text messaging application be retrievable with Whatsapp? i.e. Can I receive messages from contacts that do not use Whatsapp?

Question: I tried to download Whatsapp on my android…Whay am I asked to enter a credit card or paypal account?
Hello Admin. I plan to travel to Morocco and Spain for a month. I have an iPhone 6+ that is now unlocked. I plan to insert a new SIM card once there from some company like Vodafone. This will thus replace my current AT&T SIM card. It will also thus get me a new cell phone number. So if I want to use WhatsApp while traveling to make phone calls, will I need to load up the new number? You had an earlier post on “Changing phone Numbers”. Do I follow these steps? And then when I return to the US, after I reinstall my regular AT&T SIM card, do it do the same process? Thanks for your help on this.
You can keep on using the original number as the phone will have it stored on Whatsapp unless you update Whatsapp while you are there. You will however use the new simcard’s data plan to transmit and receive messages unless you use WiFi in which case it will be using the internet off the WiFi connection
