What is difference between AT&T SB67138 and SB67158
1760649
I think they have answered the question. it has to do with the handsets. However, I must inform you that we returned the phone. It was not user friendly, and one line would stay busy all the time. The sound quality and the buttons were not very good. I have since purchased a Panasonic expandable system, and it took 10 minutes to set up. We even called ATT and they could not figure out the problem. Good luck

SB67158 is the Main Dock - The model you will NEED to plug the lines into and broadcast the wireless signal. All other SB671... model numbers will be compatible with the SB67158. SB67138 is a large dock SB67108 is the cordless smaller version. My office is set up with the SB67158 and (2) SB67108's. I can add the SB67138 at any time without needing phone cords.

I bought the less expensive one, the SB67158 . From what I see what I bought was the BASE only and I also bought 4 additional handsets. The SB67138 which is $82 MORE just includes one handset. Mine just had the base this more expensive one has the base and an extra handset. Additional handsets are $89. We LOVE this phone, had no problems and have had it 6 months, handsest hold a charge fine, sound is great.,

Not sure what the difference is. I have a data plan with AT&T; and I often switch phones.

I didn't know they were different. I have an AT&T phone and it fits perfectly. Sorry I can't help more :/

One is a plunge router the other is fixed. So it is not an apples to apples comparison. However I used the 621 plunge router. I have a 2 star review of I on Amazon I did not like it for 3 primary reasons: bad plunge and debt control mechanism, bad chip clearing due to the vacuum system and tendency to tip over due to the narrow base high handle combination. Because of these issues, I caould not recommend 621 at all. 618 is a fixed base and its handles are really low and it does not have a vacuum mechanism. That means that it will not have the 3 issues I listed. Given the two choices you provided, I would go with 618. Look at a different brand for a plunge router. I hope this helps.

The larger of the two sizes. However, it may not get internet with a non-AT&T; card. I could not get data to work on another network, due to built in internet settings that didn't seem to be changeable.

Well, the one in this picture has the at&t logo on it. You should look for one that says International Version for the unbranded one. That way you will receive all available updates for the phone and not just the ones at&t decides you should get.

I believe the only difference with the two different models is that the international version uses HSPA+ vs the US model that works on LTE/4G. I'm currently using mine with AT&T; on HSPA+ and am very happy with the data speed. I cannot speak for other carriers at this time.

I am not sure if there is a difference. Mine is a 4G and I seem to get 4G speeds with it on AT&T.;

I think you mean SB6180. The SB6180 is supposed to be sold only by ISP's. That is one difference.Performance is much different:SB6121: 172Mbps download / 131Mbps upload.SB6180: 300-343Mbps download / 131Mbps Upload.The speed capabilities of the modem's are quite different.I would purchase the SB6180 again without a second thought.

Both models are available as retail and non-retail items (e.g. end-users and companies). As far as DL/UL performance..SB6121: 172 / 132 Mbps Down / UpSB6180: 343 / 132 Mbps Down / UpTLDR: The SB6180 offers nearly double the download performance.

I cannot tell you as I do not have T-Mobile. I can suggest you call T-Mobile and ask them if there any differences in phones.

As I wrote in my review it's not new, not working properly and is not the one advertised. AT&T; has no international versions, only locked phones for US. My advise is to don't make the same mistake I did.

I don't know. What I would do is check with your local AT&T; but DO NOT buy it from them, just either call them or go and ask them.
