Eve V SIM support

v

#1

Thanks for all the awesome work everyone part of the Eve @Team has been doing to get the best possible devices out to backers. I recently saw an article about how Google will ship Project Fi users data only SIM cards that draw from your existing Fi data plan. As a Project Fi user and a Eve V backer I was wondering if the V has a SIM card slot and support for something like this. Thanks!


#2

Current model of EVE V does not have SIM slot. New model (slightly different) to accommodate SIM slot and antennas will be produced later.


#3

As of right now, a SIM version is not available but might be in the future


#4

I think it would be interesting if the V team could come up with some sort of SIM card that fits into the Micro SD slot (if there is such a device, it would be of use to owners of the V as well as others). That would provide an upgrade for those who would like LTE capabilities for their V


#5

No chance … You need more hardware than just slot for the SIM card …


#6

You would then have to integrate an LTE module and antennas into the micro sd which is behind two layers of aluminum, that can technically not work^^

And you are limited through the SD slots write/read speeds, but this is not the biggest issue.


#7

Whats the likelihood that esim will do away with a sim hardware requirement anyway? I don’t know much about them, is it soonish or years away? (appreciate you’d still need antennas etc)


#8

Esim support would be nice


#9

Why couldn’t the wifi antenna be used for both LTE and wifi?


#10

The LTE antenna needs to be tuned for the specific radio bands it will be supporting. That’s why its hard to make a phone that will work on any carrier, generally you need a separate antenna for, say Verizons CDMA than you do for GSM radios


#11

Because they use different frequencies and you do still have no LTE transmitter that is connected to the wifi antenna.
It is just a different technology.

That is not correct though, every phone works with every carrier and nowadays even on every country (before smartphones there were phones that did only support local bands and not all bands internationally bat that is long gone. More here)


#12

Here in Canada we can’t use every phone made for, as an example, China as some of our carriers use LTE band 4 which isn’t always included. Similarly, a network like TELUS doesn’t support 2G as they migrated from CDMA to LTE. Moving off topic, but if the V did have LTE support they’d have to ensure all combination of bands and I’m sure that’d be harsh on the battery or result in multiple skus! I think even Apple has multiple skus for the iPhone (cause they can!)


#13

True, but I’m fairly confident there is only two hardware versions of a few of my phones. A Euro version and one for the rest. I may be corrected but I don’t believe there needs to be more than that.


#14

Not true. There are still a lot of GSM-only phones, which for use here in the US means you can’t use the biggest carrier in the nation. I’ve had to use a GSM MVNO here on my Lumia 950XL and it’s definitely a step down from Verizons network where i live.


#15

The iPhone is still pretty much the only phone that supports all bands and technology, and even they require you to have a different model for each (i.e. a Verizon iPhone will not work on AT&T, etc).

Hopefully eSIM will solve some of these “first world problems”, but knowing how stubborn American telecommunications companies are, it may take an act of nature to force the move.


#16

I think that is just Simlock what you are refering too :wink: They just force you to pay to use your phone with a different carrier than you have bought it.

These are the definitions of the UMTS Bands, LTE Bands

Here you can filter for which bands each phone should work

And you are right not every phone supports each frequencies, but every phone should work everywhere on the planet (where cellular network exists :wink: ) because they just switch back to an older standard if there is no fitting LTE

Where do you get a GSM-Only phone? You cannot even access the internet with these, because the speed is nearly non-existent.


#17

I’m sorry, i should have been more clear. In the US we have two competing cellular technologies, out of the five biggest carriers in the country, three of them use GSM/UMTS+LTE/HSPA, and the other two use CDMA+LTE. When i refer to a GSM-only phone, i mean that these phones are incompatible with three of our biggest mobile carriers here. The issue here is that carriers such as Verizon not only use CDMA as their fallback/low-bandwidth radio, but they also use a different LTE band than all GSM/LTE phones do. For example, even though my Lumia 950 XL supports LTE, it doesn’t support LTE band 13, which is what Verizon uses as their main LTE band. And this is typical of all “world phones”. Confusing, right? Add to this that Verizon requires every phone that supports their frequency bands to go through an expensive certification process. In Europe everything is pretty much all GSM-based but here in the US is a different story. We have all these antiquated CDMA networks that are going to take years, if not a decade or more, to completely replace with more modern, widely compatible technologies such as VoLTE. This has little if anything to do with SIM-lock, as all Verizon-certified phones are unlocked from the factory these days, and you could actually use them on a GSM carrier, but unless they are fully GSM capable they will operate with reduced functionality on those networks.

The main point of all of this is you can’t just slap an LTE modem and an antenna into a device and have it magically work on all LTE networks. Unless, of course, you want to alienate your US market. A lot of people here depend on carriers like Verizon because they simply offer the best network coverage here. That is why, and hopefully this statement makes more sense now, “It is hard to make a phone/device that works on every carrier”. Because it literally requires large amounts of money and jumping through hoops to do so.

Okay Thanks for clearing that out, I was not aware of this :slight_smile:

But I think Eve will Support all major LTE Bands with the V LTE :slight_smile:


#19

I believe you and i are talking about two different things. Yes, all cell bands are the same, but the technology within the phone to access them is different.

This is why (in the US) AT&T & T-Mobile phones cannot be used on Verizon & Sprint, and vice versa. Unless Verizon has changed something, they didn’t used to use SIM cards. They used a different technology, so that the phone couldn’t leave their network.

AT&T on the other hand did as you described, where they locked the SIM to their network.

Keep me informed when the new model supports SIM
