IYurophu iye yamukela i-GSM ( Global System for Mobile Communications ) njengoba izinga layo lokuxhumana lamanje lifani ne-United States, okwakushiya izinkampani ukuba zenze amazinga abo, okuholela ekuxhumaneni amanethiwekhi okungahambelani.
Uma uhamba eYurophu noma emazweni amaningi ase-Asia futhi ufuna ukusebenzisa ifoni yeselula kodwa futhi ufisa ukugwema ukuzulazula izindleko, izinga elijwayelekile le-GSM lenza kube lula ukuthenga ifoni esebenza, kodwa kunezinto ezithile okudingeka wazi ngokuthola inguqulo evaliwe esebenza phesheya.
Ngenxa yokuthi udinga idivaysi engavumela ukuthola ama-double-band kumakhadi we-GSM kanye ne-Subscriber Identity Module (SIM) futhi amafoni amaningi athengiswe e-United States "avaliwe" ku-carrier eyodwa ne-SIM khadi, kuzodingeka uthenge ivuliwe ifoni uma unethemba lokuthola ukwamukela eYurophu.
Ukushayela eYurophu: Amakholi we-GSM avuliwe namakhadi e-SIM
Ukwenza ucingo eYurophu uzodinga i-GSM ye-double-band GSM kanye ne-SIM khadi. Amazwe aseYurophu asebenzisa ama-double-band frequencies of 900 kuya ku-1800 kanti iMelika ngokuyinhloko isebenzisa 850 kuya ku-1900.
Uma uthengela ifoni ye-GSM evuliwe , uzodinga i-tri-band 900/1800/1900 (noma u-850/1800/1900) noma i-quad-band 850-900-1800-1900 uma uhlose ukuyisebenzisa e-US kanye naseYurophu. Ungasebenzisa ifoni ye-tri-band 850-1800-1900 evulekile eYurophu, kodwa uzobe ushiya ukusabalalisa ku-band band ka-900, okuyinto yeqembu elivame kakhulu ukuxhumana kwefoni yomhlaba wonke.
Izinkampani eziningi e-US zithengisa amafoni omakhalekhukhwini avaliwe ahlinzeka ngokukhetha okukodwa kwe- SIM khadi ukuze kusetshenziswe ngocingo ngalinye elixhunywe kumphathiswa othile, okusho ukuthi ngeke ukwazi ukusebenzisa lawa phesheya. Ukuvula amafoni weselula ngakolunye uhlangothi, yilokho okudingayo njengoba kuvumela ukusetshenziswa kwanoma yiliphi i- SIM khadi, uma nje amakhono okuvama akhona.
Ukuthenga Ifoni Yakho ne-SIM Card Ngaphambi Kesikhathi
Kubalulekile ukukhumbula lapho uhamba emazweni omhlaba okufanele uzinakekele zonke izidingo zakho eziphathelene nefoni ngaphambi kokuba ushiye umhlabathi wase-US, ikakhulukazi uma uhlela ukugcina insizakalo yakho efanayo futhi usebenzise isevisi efanayo ngaphandle.
Ungabheka inkampani yakho yase-US ukubona ukuthi yiziphi izindleko ezihambayo ezizosebenza, kepha ngezindleko eziphansi zamafoni omakhalekhukhwini nama-SIM amakhadi angaphandle, kungase kube ngcono ukuthenga nje ifoni evuliwe njenge LG Optimus L5, edayisa okungaphansi kwezingu-$ 100 , futhi ungacela nokuthi umphathi wakho avule ifoni yakho evalelwe okwamanje.
Ikhadi le-SIM isitembu esithunyelwe nge-SIM yisimo senhliziyo nobucholu beselula futhi kuyodingeka ithengwe kusuka enkampanini yakho ezweni ozoya kulo ngaphambi kokuba usuke. I-SIM khadi izonquma inombolo yocingo futhi ivumele ukufinyelela kumasevisi athile asekelwe ngeSIM khadi. Amanani ahluka ngezwe namasevisi, futhi ngekhadi elikhokhelwayo , cishe uzothola amakholi angenayo angenakunqunywa kusuka kunoma yikuphi emhlabeni, isikhathi esithile sokubiza samahhala, kanye namanani angama-distance aphansi (cishe uhhafu we-Euro ngomzuzu).
Ukuthola Amakholi Avuliwe Namakhadi E-SIM
Kungakadluli ukuthi ubukhulu kakhulu ekuthengeni umakhalekhukhwini wakho kanye nekhadi le-SIM e-United States evela kumdayisi owazi ukuthengisa nokuqasha amafoni omakhalekhukhwini ukuthi asebenzise ngaphandle.
Noma kunjalo, manje usungathola lokhu kusuka kumhlinzeki wakho wesevisi waseMelika, futhi.
Enye inzuzo yokuthola ikhadi kusenesikhathi ukuthi inombolo yefoni yakho ifakiwe emakhadini, ngakho uzokwazi ukunikeza leyo nombolo emndenini nabangani futhi usebenze i-SIM uma ufika lapho uya khona. Ungakwazi ukwengeza kalula isikhathi sokushaya kwi-SIM yasekuqaleni ngakho akudingeki ushintshe izinombolo ngaso sonke isikhathi lapho uphuma isikhathi sokushaya ucingo.
Lezi zinsuku futhi akulula ukufika ezweni futhi uthenge iSIM khadi ngenani elifanele kakhulu. Amakhadi ase-Italy, afaneleka unyaka, abe namakholi angenayo angenayo nemilayezo, futhi akuvumele ukuthi uthenge amaminithi lapho uya khona noma ugcwalise kunoma yiziphi ezinye izindawo eziningi, kufaka phakathi ama-newsstand, alayisha amafoni.
Ungaphinda uqasha iselula ye-GSM, ezinye zazo eziza ngokuqashisa ngezimoto kanye nokuqasha.
Noma kunjalo, ukuqasha efonini kanye nesilinganiso esiphakeme sokusetshenziswa ngokuvamile kuvame ukuthenga i-GSM ifoni engcono kakhulu; kungenzeka usindise ngokwanele ukukhokha ifoni ohambweni lwakho lokuqala uma wenza izingcingo eziningana.
