How about the new M690

Advantage 1: Cost-effective.

2. The color is beautiful (orange).

3 Support a lot of functions, (except handwriting and FM).

Disadvantages: 1. Poor battery life.

2. The workmanship of the press twist is rough.

3. You can't hang the mobile phone chain (no hole).

The shortcomings of frequent crashes have been fixed at the end of 2006!!

The M690 is now perfect.

It is recommended to switch to a high-power battery!

Wrong on the first floor, 690 is a smartphone.

The quality of Xia Xin is good, not so bad. This one is new again. I support Xia Xin.

Xia Xin's sound quality is also very good. The photo effect is also very good. And the cost performance is definitely higher than that of Soai, and the small functions in terms of details are also very good.

The quality of Suo Ai is not much better, especially the rocker, which is easy to break and will not take long.

Or K750C is better, full of features, and the battery is also more durable, this one that my girlfriend and I both use. I basically don't consider domestic mobile phones, and I hope that domestic products can be high-quality.

Doesn't buying Nokia solve the problem of being both patriotic and affordable? It is recommended that you buy a Nokia phone!

It is recommended that you buy nokia

If you have to buy one of the two machines you mentioned.

That's still Suo Ai. It's really not that I'm unpatriotic. But Xia Xin is really impressive.

Nokia is not made in China! The best in China is Lenovo, which has a beautiful appearance and good after-sales.

If you want to buy a durable thing, it is backgammon, wear-proof and shock-resistant, not afraid of falling, I used to sell mobile phones, and I dared to shoot when I tried the machine.

The time of day is reached. Buy him, his current technology is already very good, and there is Bluetooth technology, which is beyond the reach of other brands in China. And his ** is relatively low, and the after-sales service is also very good.

I am in the mobile phone industry, if you must buy domestic, then it is best to buy domestic first-line brands, it is recommended that you use Bird, Lenovo or Xiaxin. The rest is best left unattended.

There is no good repair of mobile phones, expensive and low success rate, and selling second-hand ones is worthless.

This is the reason for the size of the format! Your friend sent it to you on his mobile phone, and you can definitely send it back to him! It was originally his mobile phone!

It is recommended to check the manual to adjust the parameter settings of the MMS item, such as the port number, access point or something, all restore the default value, let other mobile phones send you again, if it is still a flower, it proves that it has nothing to do with your mobile phone, it is a problem with the network operator, you have to find the operator of your SIM card, mobile or Unicom.
