C2 Jolla Community Phone - 4G LTE bands/channels/frequencies

[teleshoes]

i cannot find a reliable source for the 4G LTE bands available in the modem of Reeder S19 MAX PRO S.
does anyone happen to know what bands are supported?

it would be really nice if the same LTE bands as the 10 III are available, but i doubt that will be the case since 5G is not supported.

Them being entirely different phones makes that unlikely.

@teleshoes

5G/NR support has no bearing on 4G/LTE band support for obvious reasons.

there aren’t that many modems to choose from, and also while they are manufactured by different companies, they were both pre-existing devices selected by the same company targeting the same markets.
it is (was) a reasonable hope.

@attah

5G/NR support has no bearing on 4G/LTE band support for obvious reasons.

except of course it does? for two different reasons:

1. the same component, the modem-rf module, controls both nr and lte
2. this means that Jolla is not looking for RF parity with their existing ‘flagship’. the 10III+IV+V will all support 5G on sailfish, and the C2 will not. this suggests that they dont give a fig for only supporting phones that support a superset of the current RF.

i hope you understand better, now, where i’m coming from.

This is true; but we are fairly sure these are different.

@teleshoes

they were both pre-existing devices selected by the same company targeting the same markets.

I don’t think the selection goes much beyond “will work fine” - as if there were many options.

@teleshoes

except of course it does?

No. I work with this.

@teleshoes

the same component, the modem-rf module, controls both nr and lte

…and a key functionality is to be able to listen to both at the same time.
For 5G it is even to be able to use them at the same time (even before considering things like dual-sim).
They may or may not be in the same IC, but different set of gates.

While some 5g is deployed at nor near classic 4G frequencies - a big thing is also enabling frequencies that will never see 4G.

@teleshoes

this suggests that they dont give a fig for only supporting phones that support a superset of the current RF.

Parse error.

Also would like to know the bands. Really have missed the Meego UI since my N9 and this seems like a great way to support but would want it to be usable with my telco.

Jolla Community Phone Q/A

Concerning LTE bands… the new Motorola Moto G04s also uses the Unisoc T606 SoC, so the LTE bands should be the same for the Jolla C2 (I prefer using “C2” to “CP”, on an unrelated note…): Motorola Moto g04s: Technische Daten, Test, News, Preise (in German, but the table should be self-explanatory for English readers as well). @teleshoes According to said table, at least Band 5 should be available for the US.

[teleshoes]

yes, i’ve heard the same info, but i would like official confirmation.
btw, to the best of my knowledge, band 5 is not actually used in the USA, except in one small part of one city that is 1800km away from me (namely, Miama, FL). bands 2 and 4 are the main ones. (band 4 is present on 10 III, but not band 2, and i get ok reception, but never good)

Many thanks. Seems this won’t work for me though sadly.

According to the document “Verification of Conformity” for the product the Jolla C2 supports the following 4G bands:

RX:
LTE Band 1: 2110-2170 MHz
LTE Band 3: 1805-1880 MHz
LTE Band 7: 2620-2690 MHz
LTE Band 20: 791-821 MHz

TX:
LTE Band 1: 1920-1980 MHz
LTE Band 3: 1710-1785 MHz
LTE Band 7: 2500-2570 MHz
LTE Band 20: 832-862 MHz

thanks for confirming. absolutely zero overlap with USA LTE bands.
