Dear [Friend's Name],

I hope this letter finds you well. I recently heard that you bought a new mobile phone and I couldn't help but be curious about it. Can you please tell me what kind of mobile phone you purchased? I'm also interested to know how much you paid for it. Lastly, I'm eager to learn what you like most about your new phone. I'm sure there are some exciting features or aspects that caught your attention. Your insights will help me understand more about the current trends in mobile technology and may even influence my own future purchase decisions.

Looking forward to hearing all about your new device!

Best regards, [Your Name]
