Dual Sim vs Single Sim

[wasim sallam]

is there any differences between dual and single sim of 950XL?
I mean like performance and of course mobile data connection or call quality?

This.
Lumia 950 XL Dual sim:
LTE max data speed DL: 150 Mbps (Cat 4)
Lumia 950 XL:
LTE max data speed DL: 300 Mbps (Cat 6)

As they are different builds there probably is some but I've used both and have to say there is no noticeable difference..

A difference is the max download speed on LTE but because nearly no provider has CAT 6 "towers" you will not notice this difference.

950 XL
LTE max. data speed DL: 300 Mbps (Cat 6)
LTE max. data speed UL: 50 Mbps (Cat 6)

950 XL dual
LTE max data speed DL: 150 Mbps (Cat 4)
LTE max data speed UL: 50 Mbps (Cat 4)

thanks for clarification.
I think 150 Mbps us enough for me and I really need a dual sim phone.

Furthermore I read that Visual Voicemail is currently not support on Dual SIM phones.

Was just about to add this.. Dual SIM phones with Windows do not support visual voice mail as of yet.

Just want to add that Cat4 phones (dualsim) can't utilize 4G LTE-A network which offers up to 300 Mbps theoretical speed (real world speeds upto 100 Mbps with Cat6 antennas), so they would work like normal single 4G LTE (150 Mbps with real world speeds upto 30Mbps).
So if speed matters, go for the single sim with Cat6 radio.

You will get better battery life in cities with good cell reception versus cities with poor cell reception.

I think this is a given for pretty much any cell phone.

Visual Voicemail on the single-SIM works perfectly on AT&T! I just got the PIN prompt and voila, it works great. LTE too. Everything is perfect. So glad I returned the $700 hacky dual-sim one and got a sub $600 gently used one on Swappa!

What a pleasant surprise. I see no reason for anyone to buy the dual-sim...Microsoft should have launched the single SIM in the states. Oh well.

Except ppl complain why they only get half a days charge and wonder why and blame the phone

Well then, it's good that Microsoft didn't ask just one person what to do. :wink:

I need two phone numbers and I don't want to carry two phones all of the time. I seldom get voicemail because my phones are with my pretty much always. So, in weighing the convenience of carrying only one phone against the inconvenience of not having visual voicemail, I choose carrying one phone. And I hope that Microsoft is able to do a software update to add VVM to dual-SIM devices. I also know that they can't do a software update to add a second SIM slot to the single-SIM devices.

They make both devices because different users have different needs.

I think the difference between cat6 and cat4 is not noticeable in your "usual daily use" except if you watch 4k Netflix on your mobile device and using your data and not wifi^^

Here in Europe Dual SIM is the best thing that could have happened. There are alot of offers here (similar to slickdeals) where you can get a data only SIM for free/very little money (I'm talking about under 5 bucks). So for us/me it is very conveniant to have one contract with just a flatrate/unlimited calling and no data and then have another contract with free/cheap data. So for around 10/15 USD you can have everything with 2 SIM's

That's great! Dual-SIM fits your needs perfectly. My point is you are an edge case, at least in the US...99.9% of Americans have one single phone line and one single need for a SIM. But Microsoft decided to offer the dual-SIM model only in the US, which has serious tradeoffs with US carriers. That frustrates and confuses their target market. They are offering only a dual-SIM to the masses who just want their $700 device to work with their carrier (yes, VVM is a big deal to most). Makes little sense to me personally. Instead, you have to find an international model originally produced for China and import it if you want it to fully work with a US carrier. What?

My point is, for the vast majority of people in the US, the single SIM model will be better. I read somewhere that AT&T will not support VVM on a dual-SIM phone period, so a software update may not be able to fix things.

I stand by my point. Single SIM is the way to go in the US unless you have a very specific need for two lines on one device. I do not. YMMV. Microsoft either needs to offer the single-SIM variant in the US or pressure AT&T to fix VVM incompatibility.

I personally don't need a dual sim phone but I can think of reasons people would want one. For example: avoiding having to carry two phones - one for personal use and one for work. Pop in a second SIM and you're done. Quite a blanket statement you made.

That, I agree with.

Yeah, I love the concept of consolidating my work and personal line on the weekends, but alas my work device is Verizon. It'll be a huge benefit to some, but confusing to everyone else IMO. Sorry for the sweeping blanket statements, but I think most average consumers will avoid the dual-SIM phone in the US because they just don't need it. IMO as every internet post is.

 

[feereless]

i don't know of any carrier that can even hit 150mbps anyway... in the future with 5g? maybe

In Canada my dual sim is awesome. Our carriers still charge very high roaming fees. I travel to the US a fair bit and always swap my sim out and use a US sim. Will be great keeping both installed and love the interface of switching and dealing with both sims. I wanted the dual sim and the MS on-line store in Canada only offers the single sim. Thankfully the website is wrong and they actually ship the dual sim. My carrier the largest in the country only provides visual voice mail to iPhones which sucks. So having the dual sim in Canada I don't lose that feature as it is not available.
