Theoretically, not necessarily as long as the mobile phone supports JAVA extensions. I found that many domestic mobile phones support JAVA extensions, but they just can't install stock trading software. According to my experience, I recommend several mobile phones: ① Motorola E2, which is my mobile phone and equipped with two mobile phone stock trading software, great wisdom and straight flush, both of which are good; ② Nokia 3110c; Nokia's mobile phone supports these two softwares very much. (3) Nokia 5200, now as long as 950 yuan, fully meet your requirements. It's just that the screen is a little small, 1.8 inch. The resolution is a bit low, but the software support is good.
Be careful not to buy the domestic stock-trading mobile phone introduced on TV shopping. Almost all of them have installed a charging stock trading software, but they can't be upgraded yet, and the quality is not good. However, the Lenovo i908 bought by a friend of mine is not bad, with great wisdom and high speed, but it does not support the entrustment of our brokerage firm. We only have one Huazhong Securities here.
I have used another investment link for more than a month, and I don't feel very good. I don't need it now. I don't know how it is now. I hope it's good.
