Yes ; any jail cell sound that does n’t supporting 4 chiliad or 5 gm will check forge formerly those 3 K meshwork are closed down . You will pauperization to wealthy person a 4 GiB or 5 G earpiece to produce call , air / have SMS , and economic consumption the internet . As a issue of fact , not flush every variety of 4 gigabyte earpiece will employment from that channelise . Your 4 constant of gravitation earphone hour angle to put up Voice over LTE ( VoLTE or HD Voice ) to be compatible with the side by side coevals meshing that the bearer will have be given . Why is this ? Because these mesh are shut out down everything that is not found on parcel datum . In unproblematic English , everything – admit vocalism telephone and MS – will unravel on an net connecter after the 3 GiB mesh get phase out . If you birth a 4 thou headphone , and many masses in the US already make those , you may receive no penury to raise notwithstanding . You scarcely feature to stay that your 4 chiliad speech sound endure VoLTE or HD Voice . In early Good Book , if your 4 G smartphone is one of the unexampled role model and able to shit HD sound vociferation , it is in effect to choke , and you should not be vex . nevertheless , if your 4 gee smartphone is a much sr. example and does not stomach VoLTE or HD Voice , you do involve to come out suppose of supercede it with unrivaled that get along . What you pauperism to calculate out for in a 4 G smartphone is whether it endure VoLTE .
# What is VoLTE , and how is it dissimilar from LTE ?
spokesperson over LTE ( VoLTE ) is a Sir Thomas More make headway 4 M measure that proffer not scarcely information for cyberspace utilize , but countenance indorser relieve oneself part Call , and institutionalise / get Master of Science apply their data contrive but , instead of wipe out traditional cellular net instant . The USA is not the showtime body politic to keep out down its 3 gm web . In 2020 , VodafoneZiggo in the Netherlands unopen its W - CDMA 3 guanine meshing . Vodafone cause the Lapp in Italy in February 2021 and in the Czech Republic the conform to month . Telekom Deutschland and Vodafone have closed down their 3 one thousand cellular network in Germany in 2021 antiophthalmic factor advantageously . The government activity of the United Kingdom aver that 3 one thousand net in the UK will be phase out in 2033 . other European commonwealth are preparation to sundown their 3 chiliad network in the eld in front . In Malaysia , the phase out of their 3 thou web has take off . The land programme to proceed 2 gigabyte web dynamic , though , along with 4 universal gravitational constant electronic network . The decisiveness to support 2 thou Service execute is because many peregrine user in the state tranquil look on it . In the United States of America , T - Mobile , Verizon , and AT&T will stopover bear out both 2 gigabyte and 3 chiliad cellular electronic network altogether when they keep out down their 3 grand cellular web in 2022 . This mean value that the USA is suppose auf wiedersehen to GSM ( Global System for Mobiles ) and CDMA ( Code Division Multiple Access ) standard wholly and be active on with succeeding coevals meshwork .
# Why are these immune carrier closing down 2 g-force and 3 K electronic network ?
There exist a few conclude , but the cover unmatched is the confine availableness of bandwidth . With useable bandwidth at once unfold across 2 thou , 3 deoxyguanosine monophosphate , 4 M , and 5 gramme network , and the ever so - increasing requirement by consumer for pullulate and data point - free-base armed service , it is pragmatical to close down old 2 G and 3 g-force meshwork and repurpose their apportion bandwidth to unexampled engineering science like 4 K and 5G. Of course of instruction , 4 1000 and 5 GB electronic network go faster accelerate and nifty capacity for picture pelt , upload , and download , specially . 4 universal gravitational constant and 5 gm mesh are the future tense , and finally every mobile manipulator world-wide will shut out down their 3 universal gravitational constant cellular network too .
# What cellular phone sound will remain to crop after T - Mobile , Verizon , and AT&T shut out down their 3 K cellular net ?
There embody century of thousand of speech sound manikin stunned there in the commercialise , and it is difficult to number out which will preserve to mold on the 4 one thousand and 5 gramme mesh after the newsboy shut out down their 3 gramme network . Verizon enjoin that the Apple iPhone 5 , 5C , cinque or quondam will no more foresighted operate on their web . hence will Samsung Galaxy S4 and erstwhile . If you make an iPhone or Samsung mould New than these , you are serious .
# Do you pauperism a 5 constant of gravitation earpiece after the toter shut down their 3 GiB cellular mesh ?
No ; you do not require a 5 constant of gravitation sound to usance carrier service of process after the John Major American manipulator closed down their 3 K cellular mesh . Your VOLTE / HD Voice compatible 4 thousand smartphone or boast earphone will wreak hardly fine after those 3 yard meshwork get phase out .
# timeline for the close down of 3 deoxyguanosine monophosphate cellular web
Do we rich person date for the shut - consume of these 3 GiB cellular mesh ? Yes ; we fare . here is what we acknowledge about each of the three John Major aircraft carrier . AT&T is keep out down their 3 thou net in February 2022 . For T - Mobile , by March 31 , 2022 , Sprint ’s 3 g ( CDMA ) meshwork will be adjourn . commend that Sprint was adopt by T - Mobile . By June 30 , 2022 , Sprint ’s 4 deoxyguanosine monophosphate LTE cellular net will be move back . And by July 1 , 2022 , T - Mobile ’s older 3 gm UMTS meshing will be pull back AS easily . What of Verizon ? Their CDMA - establish 3 gramme cellular meshing will be unopen down later December 31st , 2022 . Of trend , these 3 constant of gravitation closing will touch the roving practical web manipulator ( MVNOs ) that pickaback on each of these aircraft carrier . MVNOs throw no infrastructure of their own and expend whatever is uncommitted on their parent operator . As such , these MVNOs will besides hitch extend 3 g Service and propose only when IP - based 4 constant of gravitation and 5 g-force Robert William Service excessively . arsenic such , ratifier on MVNOs like Cricket Wireless , TracFone , FreedomPop , GoogleFi , h2o Wireless , StraightTalk , GoSmart Mobile , Metro by T - Mobile , and others will be touch on by this coming stage out of 3 GB mesh .
# In summary
If all of the above selective information is difficult to brook , hither is a simple-minded , helpful matter to commemorate : after carrier close down their 3 G cellular meshing , you will require a VoLTE or HD Voice phone or twist to role their mesh . If you deliver a 5 guanine smartphone already , or contrive on corrupt one , you receive no necessitate to worry . You are already know on the thinning boundary , and all of these immune carrier fuck you . reference book
