Sample Answer for an Informal letter

The IELTS informal letter to friend is one of the IELTS general writing task 1: informal letter samples frequently-asked in the test. Practise it until you reach the optimum level in writing.

You want to sell your mobile phone. You think a friend of yours might be interested to buy it from you. Write a letter to your friend. 

In your letter:

Explain why you are selling your mobile phone.
Describe the mobile phone.
Suggest the mode of payment to your friend.

Dear Shasna,

How are you and your family? Hope everything is fine. I heard that you are looking for a smartphone in the 20,000 and 30,000 range. Fortunately, I too wanted to sell my smartphone for 25,000. 

I bought the Apple smartphone (iPhone 11) for 50,000 a year ago, and I’m planning to buy the new version (iPhone 12) next month. The reason why I go for the new version is the 6-inch widescreen and the latest camera features. I can watch high-definition videos on a 6-inch screen and take tons of pictures.   

My iPhone 11 is no lesser than other smartphones in the market. It is still one of the go-to mobile phones for its processor, RAM and storage spaces. In the last year, I had no issues with my phone like battery drainage, stuck up or any features. 

If you are interested in buying my phone, just drop me a message. I will share the GPay link so that you can do the payment online.
