As i know the operators prefer 900 yet and 1800 if 900 not working of weak in the aera.

Could the poor signal be the fault of your service provider? Phones with external antennas are not so cool

@Angelgirl. We are looking at comparisons here, actually. Phone to phone, at same location, on same network.

@blackspot, if Aivar is correct, external antenna is not the solution

@angel u get your point, bv if it effects better reception and next to it longer batt performance it worth imo

When two same phones on the same network are close to each other on the same table - even in this case one of them might choose signal from one GSM-tower and the second phone from the other GSM-tower. Usually it happens in cities where are lot's of GSM-towers [stations] and their coverage area overlap.
Let's say, one mobile phone is Nokia 5110 and the other SonyEricsson T68i. Nokia 5110 works only at 900 MHz, so it chooses the reception signal from nearest GSM 900 tower. But SonyEricsson chooses signal from GSM 1800 tower, as it is the higher and therefore prefered frequency.
900 MHz has very good penetration, 1800 MHz not so good.
So in this case the reception of Nokia 5110 might seems much better than the reception of SonyEricsson. BUT at the same time one of them uses frequency 900 MHz and the other 1800 MHz.
Even at the same frequency phones close to each other might choose the signal from different GSM towers.
Conclusion: without special technical equipment it's impossible to compare which phone has better reception, even close to each other.

@ Angelgirl
You mean, if SE would make a phone with external antenna? I'm not a specialist, but I'm sure that external antenna with nowadays technique could give a little advantage. But how little, it's possible to measure only in lab conditions.
But imagine a mobile phone with 5 metre antenna
locating in the very week signal area in the deep forest where usual phone is out of the network. Of course it would receive a signal, as it extend above the barrier (a tree).

I never said the external antenna was the definite solution. But it would probably help to look at the difference and learn from it.
The very first models of phones with internal antenna were known to have very weak reception but they tried to compensate it by somehow in the later models by increasing the effectiveness of the internal antenna (position or shape, i don't know) and increasing the signal received by the antenna using a signal booster (pre-amp) which ultimately increases the battery consumption. Todays phones with internal antenna probably have comparable or even better reception than some older phones with external antenna. If we combine both technologies we might achieve a phone with better reception.
In the point of view of the manufacturer, however, we have to consider also design which nowadays plays a major part in marketing.
Perhaps an option to add an external antenna as an accessory for people located far from cell sites would be a good solution.
