通过实际测算可得出，在全价时段用手机打长话比座机便宜，其余时候打座机比打手机便宜。见下表： 另外我们要提醒各位读者的是，座机打长话也可以打ＩＰ电话，其价格是最便宜的，因为其长话费为０．３元／分钟（市话费另计）。打长话,手机座机谁更省钱?@黄欣 It can be drawn from the actual calculations that the long-term phone call at a full price period is cheaper than the landline phone and the cheaper call at the other landings than the mobile phone. See the table below: In addition, we want to remind you that the landline can make long-distance calls can also make IP calls, the price is the cheapest, because of its long-distance calls 0.3 yuan / minute (city calls excluded). Make a long story, mobile phone landline who save money? @ Huang Xin
