Hi everyone, I live on a farm where I only get edge on the vodacom network with a cell c sim card.
Problem is when I swaped my sim from a nokia 5230 to a galaxy pocket the internet speed is really bad but when I put it back into the nokia its okay again.
What could be the reason for this?

Does the Galaxy pocket have bad edge performance or is there something wrong with my settings?
 
It could be that Galaxy is constantly trying handover to 3G, but 3G tower doesn't give any throughput (quite common) and lot of time is wasted on these attempts. What happen if you use 2G-only (GSM) settings for both data and voice?

Cell C got in touch and said the galaxy pocket doesn't support edge on the vodacom network so I'm actually getting gprs.boo

I have just got Afrihost mobile broadband though and I get 3g on mtn.

Thanks for the help.
 
I don't believe. I would double checked with Samsung.
 
I just did a specs comparison between my 5230 and galaxy pocket and the nokia edge is rated class 30 and the samsung is class 12.

They actually pretty similar except class 12 has slightly worse download speed but much better upload.

They both seem to support the same frequencies. So I dont know whats going on.
 
Again, set Samsung to use GSM-only. It would be interesting to know, maybe Vodacom-only roaming connection suffers the same problems as many other Cell C users.
 
Interesting, Samsung don't specify GPRS coding scheme. Lacking CS-4/CS-3 would make a difference you observed. Nokia supports up to maximum CS-4.
 
The only thing I could find about the gprs specs of the galaxy pocket was this.

Class 12 (4+1/3+2/2+3/1+4 slots), 32
- 48 kbps

The first line is for multislot (EDGE), maximum speed not specified.
Second line GPRS 48kbps - maximum for GPRS is 80kbps Class 8&10 with CS-4 and 48kbps with CS-2. Based on this I conclude your maximum coding scheme is CS-2.
For comparison CS-2 bit rate is 12kbps and CS-4 20kbps, so maximum EDGE download speed for Samsung will be reduced by the factor 4/5 for multislot combination, and then reduced by the factor CS2/CS4 for coding scheme.

4/5 * 12/20 = 0.48 ---- 48% speed of Nokia.
