Dear Sir or Madam, We write to introduce ourselves as one of the largest exporters, from China, of a wide range of Wireless Module(GSM/GPRS/GPS). We have been in this field for more than 4 years. With annual sales over 500k pcs, we have much experience in doing business with wireless terminal manufactures from China , India , Europe and South American, ect. We enclose a copy of our latest catalog of wireless module at present, and hope some of these items will be of interest to you. It will be a great pleasure to receive your inquiries for any of the items against which we will send you our lowest quotations. Should, by chance, your corporation not deal in the import of the goods above mentioned, we would be most grateful if this letter could be forwarded to the correct import corporation. We are looking forward to your favourable and prompt reply. Yours Faithfully Lisa Zhang
