This damn slow internet speed...

I have two SIM cards, one China Mobile and one China Unicom. Since Unicom's network speed completely surpasses Mobile's, I've always used the Unicom card to go online. Until a few days ago, the Unicom card started acting up. Even though I still had 100MB of data, going online didn't use the data and directly deducted phone charges. I had no choice but to use the Mobile card to access the internet. As a result, when playing Rhythm Master, it used to take less than half a minute to load a song with Unicom, but now with Mobile, it takes at least 5 minutes per song, and it frequently gets disconnected. I really have no words to complain. If it weren't for connecting short numbers with my sister, I would have thrown away this lousy Mobile card a long time ago. Damn Mobile, 3G network can only be used on Mobile-customized phones, other phones can only use 2G. Damn, when will Mobile learn from Unicom? Damn...
