Izinketho zakho zokwenza iifowuni zakwamanye amazwe ngelixa uhambayo awanakulinganiswa nokusebenzisa amakhadi okufowunela nokuzingela ifonti yefowuni (ewe, ezo zikhona). Namhlanje, ungahlala udibanisa nabahlobo, intsapho kunye nabo osebenza nabo xa behamba phesheya ngokuqesha i-fowuni okanye i-SIM khadi, usebenzisa i- VoIP izicelo kwi-laptop yakho, kwaye mhlawumbi usebenzisa i-cell phone yakho yangoku.
Nantsi ingqalelo kwizinto ezixhamlayo kunye neengxaki zezi zikhetho zee-international.
Ukuthenga iKhadi lokuBiza
Nangona kungenokuba yindlela engabizi kakhulu kwi-call-based basis (kuxhomekeke kwikhadi), kwaye ngokuqinisekileyo ayilungelekanga kunokuba ube nefowuni kuwe, amakhadi okubiza athandwa ngabahambi bamazwe ngamazwe ngenxa yokuba banexabiso elimisiweyo kunye baqhelana nabantu abaninzi.
Iinkonzo :
- Kulula ukwenza uhlahlo lwabiwo mali
- Amanqaku amaninzi asebenza naphi na unayo ifowuni
- Abantu abakwazi ukukukhupha ngokukubiza xa useholide
Umgcini :
- Iifowuni ziyabhubha (nakwiibhanki zeefowuni zeefowuni ezibomvu)
- Ukufikelela kuwe kunzima kwabanye
- Kunzima ukukhetha ikhadi lefowuni ngenxa yokudibanisa ixabiso; kukho amakhadi amaninzi ngaphandle apho
Yenza Ifowuni Yakho Yakho
Le yona khetho ekhethekileyo; vela nje umnxeba wakho wamanje xa uhamba kwelinye ilizwe. Ukuba uneselfowuni engasebenza ngaphaya kohlobo lwenethiwekhi yolwazi lweselula kwindawo oya kuyo-ngokukodwa ifowuni ye- GSM ukususela kwiindawo ezininzi zehlabathi (ngaphezulu kwama-80%, kwi-GSM Association) isebenza kwi-GSM-ke uya kuba nakho benzisa ifowuni yakho apho uya khona.
Qhubeka ukhumbule, nangona kunjalo, ukuba uya kuthi uhlawulwe iirhafu zokuzulazula ngokubonelela ngomniki wakho weselula. Uninzi lwababoneleli beenkonzo zeseli banikeza iipakethi ezikhethekileyo kubahambi bamazwe ngamazwe abancinci kwaye banokumiselwa ngaphambi kokuba uhambe uhambo lwakho.
Ngaphandle kwemirhumo eyongezelelweyo, iiproveats eziphambili ziquka:
- Ifowuni yakho kufuneka ibe yifowuni ye-GSM. Nangona ezininzi iifowuni ngaphandle kwe-US yi-GSM, e-US ezinye iifowuni zeVerizon kunye ne-Sprint zisebenza kwi-CDMA ye-teknoloji yeselula, kwaye kuya kusebenza kuphela kwi-T-Mobile ye-US kunye ne-AT & T isebenzisa iifowuni ze-GSM.
- Ifowuni yakho ye-GSM ifanele isebenze kwibhande elifanelekileyo okanye ngokuphindaphindiweyo . I-GSM yase-US isebenzisa ii-1.9GHz nee-850MHz zamaqela, ngoxa i-Yurophu ye-GSM isebenza kumaziko angama-900MHz kunye ne-850MHz. Ubhedu obuhle kakhulu kubahambi bamazwe ngamazwe ukuba ube nefowuni ye-GSM ye-trim okanye ye-quad yokuhambelana-hlola nomenzi wakho wefowuni ukufumanisa ukuba umzekelo wakho unalo.
Iinkonzo :
- Unokukhetha ukhetho oluhle kakhulu
- Ifowuni yakho kunye nolwazi kwifowuni yakho ehamba nawe
Umgcini :
- Kufuneka ube nekhnoloji yeselula efanelekileyo yokufikelela amanethiwekhi angaphandle-ngokuqhelekileyo i-GSM.
- Iindleko zokuhamba zibiza (ingakumbi ukuba unayo i-smartphone ehlala idla idatha)
- Nangona ifowuni isebenza, i-voicemail ayinakho
- Uya kufuneka uhlawule ifowuni yakho, kwaye kuya kufuneka ukuba ufune i-adapters kwiindidi zeeplagi ezisetyenziswa kwamanye amazwe
Thengisa i-SIM khadi kwi-Phone yakho yeselula
Ukuba uneselfowuni ehlangabezana neemfuneko zobuchwepheshe kwilizwe oya kulo, unokuphephela iindleko zokuhamba ngeendleko kwi-carrier yakho yangaphakathi ngokuqeshisa i-SIM (umthengi wekhowudi yomnxeba) kwifowuni yakho eya kusebenza yakho ukuya kuyo.
Oku kungabizi ngaphantsi kokusebenzisa umgangatho wakho wamaxabiso ngamazwe ngamazwe okanye uqesha i-cell phone entsha, kodwa nayo ine-caveat yayo ekhethekileyo:
- Ifowuni yakho ye-GSM okanye ye-quad-band kufuneka ivuliwe . Ezinye iifowuni zingavalwa, oku kuthetha ukuba zisetyenziselwa kuphela kwinethwekhi yomphathiswa wefowuni ekuthengwa kuyo ekuqaleni. Abanye ababoneleli beefowuni baya kuvula ifowuni yakho ukuba ubacele; kwabanye, kukho ikhowudi yokuvula iifowuni, ii-hacks, kunye neenkonzo ezijikelezayo ngewebhu ukukunceda.
Iinkonzo :
- Ixabiso elingaphantsi ngokuqhelekileyo kunokuqasha iselfowuni
- Unokuthatha ifowuni yakho yangoku uhambo lwakho
Umgcini :
- Kufuneka ufumane uhlobo oluthile lwefowuni
- Kungaba nzima ukwenza ifowuni yakho ivuleke ukuba kuyimfuneko
- Abafowunelwa nabo, ukuba zigcinwe kwi- SIM khadi yakho , abayi kufumaneka ngekhadi leSIM yokuqashisa
- Uzakufuna ukunika inombolo entsha kubantu ukuba baqhagamshelane nawe
Qasha i-Cell Phone
Nangona zibiza ngaphezu kokuqesha i-SIM khadi, ukuqesha i-cell phone ye-GSM esebenza kwindawo oya kuyo ikuvumela ukuba ufikeleleke ngamaxesha onke uze wenze ucingo.
Iinkonzo :
- Ukuqeshiswa kwefowuni kufumaneka kumazwe angaphezu kwe-150 emhlabeni jikelele
- Unokuphepha ukhuseleko kunye nemali yokuxhumela eyongezelelweyo-akukho nyikimazi enkulu
Umgcini :
- Awuyi kuba noqhagamshelwano nolwazi olugcinwe kwifowuni yakho
- Udinga ukunika inombolo entsha kubantu ukuba baqhagamshelane nawe
- Ukhetho lwefowuni olukhawulezileyo, ngoko kufuneka ufunde ukuhamba ngeendlela ezintsha zefowuni
Sebenzisa i-VoIP Calling kwi-Computer
Ukusebenzisa iinkonzo zee-intanethi ezisekelwe kwi-intanethi njenge-Skype ingaba yindlela encinci yokwenza iifowuni zamazwe ngamazwe ; iyakwazi ukukhululeka xa usebenzisa i- wi-fi hotspot yamahhala .

Umgcini :
- Abanye abakwazi ukufikelela ngokukhawuleza
- Kufuneka ube kwikhomputha ukwenza iifowuni
- Kwangathi ixabiso elininzi kuxhomekeke kwindlela yokuxhuma
