What is the closest cell phone reseller to the Novotel XinQiao hotel in Beijing?

I need an authorized reseller of a good (nokia/motorolla) cell phone within walking distance of this hotel. Preferably one open on Sundays and can provide chips/international calling plans.

The nearest shops selling mobile phones to the Novotel are located in the Wangfujing(aka the Walking Street) They are open 7 days a week and China Mobile has an official shop selling mobile phones of many makes,local as well as Nokia,Motorola,Sony-Ericksons,Samsung etc.Their prices are fixed and will not bargain, their quality is guaranteed and carry the company's warranty.The Beijing Wangfujing Department Store too has a huge selection of mobiles in stock.

Buy the SIM card with number starting with "159",on this number the incoming calls are free and out going local call cost Yuan 0.25 per minute,a SMS is for 0.20.International calls made from your mobile phone are very costly about Yuan 10 per min,for that you can purchase a IP calling card available in many denominations,eg.the Yuan 100 face value card will cost Yuan 28 and is excellent for overseas calling,about 1 hour's call time to the USA.

Your hotel is near Tiananmen Square, so you are a walking distance, maybe one block or two, to Wangfujing pedestrian street, where you will find several reputable stores selling cell phones and other electronic goods.
