The mobile phone bus card was jointly launched by Unicom and Ji 'an Bus Company. Mobile phone number is also ok. No cell phone restrictions. 50 yuan. It will be more affordable to change Unicom's number. Get a Unicom 2G card (including 70 phone bills)+a mobile phone bus card when handing it over to 50 yuan. I work in Unicom, so I know better. Hmm. How interesting
