Tell me about a business of China Mobile in two cities. I'm from Shandong, and my mobile phone number is Hui Rizhao from Weifang for the New Year.

Fee-saving package: the function fee is 2 yuan/month. If you apply for a city in the province as a roaming preferential place, you can call the caller at 0. 1.2.3/min in the designated roaming preferential place and the city applying for roaming, and the caller is free. The processing mode of service package is 1. Go to the local mobile business hall with valid certificates; 2. SMS business hall handling: (1) Inter-provincial "two cities and one family": send SMS "KTLCYJ roaming area code" to 10086 for opening; (2) "One family in two cities" in the province: send a short message "KTLCYJ roaming area code" to 10086 for opening; (3) Change the roaming preferential area: send a short message "long distance area code of BGLCYJ roaming area" to 10086 to change it. Follow-up: What if I cancel? Answer: it will automatically close at the end of March! If you want to cancel in advance, you can send it to 10086.
