Answer:
Grandmother: Hello Kunal/Kriti, can you help me with my new smartphone? I'm not sure how to use it.
Kunal/Kirti: Of course, Grandma. Let me see your phone. Do you know how to turn it on?
Grandmother: I think I pressed this button here, but it doesn't seem to be working.
Kunal/Kirti: Ah, that's the power button. You have to hold it down for a few seconds until the phone turns on. Once it's on, you can swipe up to unlock it.
Grandmother: Okay, I see. What do I do now?
Kunal/Kirti: Let me show you how to make a phone call. Open the phone app and enter the number you want to call, then press the green call button.
Grandmother: Oh, that's easy. What about texting?
Kunal/Kirti: To send a text message, open the messaging app and select the contact you want to message. Then, type out your message and press send.
Grandmother: I think I'm getting the hang of it. Thank you so much, Kunal/Kriti!
Kunal/Kirti: You're welcome, Grandma. Don't hesitate to ask if you have any more questions.
