Izinketho zakho zokwenza izingcingo zamazwe ngamazwe ngenkathi uhambo zingasagcini ekusebenziseni amakhadi okushaya nokuzingela ibhokisi lefoni (yebo, lawo asekhona). Namuhla, ungaxhumana nabangani, umndeni, kanye nabo osebenza nabo ngenkathi uhamba phesheya ngokuqasha umakhalekhukhwini noma ikhadi le-SIM, usebenzisa izinhlelo ze- VoIP kwikhompyutha yakho, futhi, mhlawumbe, usebenzisa iselula yakho yamanje.
Nakhu ukubheka izinzuzo nezindleko zalezi zinketho zomhlaba jikelele.
Thenga ikhadi lokushaya
Nakuba kungase kungabi yindlela engabizi kakhulu ngekholi ngayinye (ngokuya ngekhadi), futhi akulula nakakhulu kunokuba nefoni, kuwe, amakhadi okubiza athandwa nabahambi bamazwe ngamazwe ngoba banamanani ahleliwe futhi bajwayele abantu abaningi.
Izinzuzo :
- Kulula ukubeka isabelomali
- Amakhadi amaningi asebenza noma yikuphi lapho ufinyelela khona efonini
- Abantu abakwazi ukukukhubaza ngokukubiza uma uhlala eholidini
Umthengi :
- Ama-payphone ayanyamalala (ngisho namabhokisi efoni obomvu aseBrithani)
- Ukufinyelela kuwe kungaba nzima kwabanye
- Kunzima ukukhetha ikhadi lefoni ngenxa yezindleko zokudideka; kunamakhadi amaningi amabi lapho
Letha umakhalekhukhwini wakho
Lena inketho elula kakhulu; vele ulethe umakhalekhukhwini wakho wamanje lapho uhamba phesheya. Uma unomakhalekhukhwini ongasebenzisa uhlobo lwenethiwekhi yedatha yeselula lapho uya khona-ikakhulukazi ifoni ye-GSM kusukela kuningi lomhlaba (ngaphezulu kuka-80%, nge-GSM Association) isebenza kwi-GSM-khona-ke uzokwazi sebenzisa ifoni yakho nomaphi lapho uya khona.
Khumbula, noma kunjalo, ukuthi uzophinde ukhokhiswe imali ehamba phambili yokuhambisa izithuthi ngomhlinzeki wakho weselula. Abanikezeli abaningi bezinsizakalo zezinsizakalo banikeza amaphakheji akhethekile kubantu abahamba ngamazwe aphansi futhi angasethwa ngaphambi kokuba uhambe uhambo lwakho.
Ngaphandle kwemali eyengeziwe, ama-caveats ayisihluthulelo afaka:
- Ifoni yakho kufanele ibe yocingo le-GSM. Nakuba amafoni amaningi angaphandle kwe-US angama-GSM, e-US amanye amafoni e-Verizon ne-Sprint asebenzisa ubuchwepheshe beselula ye-CDMA, ngakho-ke uzosebenza kuphela e-US T-Mobile ne-AT & T besebenzisa amafoni we-GSM.
- Ifoni yakho ye-GSM kufanele isebenze kwibhande elifanele noma imvamisa . I-US GSM isebenzisa ama-1.9GHz nama-850MHz amaqembu, kuyilapho i-Yurophu GSM isebenza kuma-900MHz nama-850MHz amaqembu. Ukubheja okungcono kunazo zonke izihambeli zamazwe ngamazwe ukuthi ube nefoni ye-trim noma ye-quad-band GSM yokuhambisana-hlola nomenzi wakho wefoni ukuthola ukuthi imodeli yakho inakho.
Izinzuzo :
- Inketho elula kakhulu yokushaya
- Oxhumana nabo nolwazi efonini yakho bahamba nawe
Umthengi :
- Kudingeka ube nobuchwepheshe beselula bokufinyelela amanethiwekhi angaphandle-ngokuvamile i-GSM.
- Ukushayela izindleko kuyabiza (ikakhulukazi uma une-smartphone edla njalo idatha)
- Ngisho noma ifoni isebenza, i-voicemail kungenzeka
- Uzodinga ukushaja ifoni yakho, futhi cishe uzodinga i-adapters yezinhlobo zama-plugs asetshenziswe kwamanye amazwe
Qasha iSIM khadi yefoni yakho yeselula
Uma unomakhalekhukhwini ohlangabezana nezidingo zobuchwepheshe ezweni oya kulo, ungagwema izimali zokuzulazula kwedatha kusuka kubathwali bakho bendawo ngokuqasha ikhadi le-SIM (ubhalisele umthamo wemodemu) efonini yakho ezosebenza okuya khona.
Lokhu kuvamile kakhulu kunokusebenzisa amanani omhlaba wonke omhlinzeki wakho noma ukuqasha umakhalekhukhwini omusha, kodwa futhi une-caveat yayo eyingqayizivele:
- Ifoni yakho ye-GSM yesithathu noma ye-quad kufanele ivuliwe . Amanye amafoni angase avaliwe, okusho ukuthi angasetshenziswa kuphela kwinethiwekhi yomthumeli wefoni ovela kuye ekuqaleni. Abanye abahlinzeki bamakhalekhukhwini bayokuvula ifoni yakho uma ubacela; kwabanye, kukhona amakhodi wokuvula ifoni, ama-hacks, nezinsizakalo ezizungeze kuwebhu ukukusiza.
Izinzuzo :
- Ibiza kancane kakhulu kunokuqasha umakhalekhukhwini
- Ungathatha ifoni yakho yamanje ohambweni lwakho
Umthengi :
- Udinga ukuba nohlobo oluthile lwefoni
- Kungase kube nzima ukuthola ifoni yakho ivuliwe uma kudingeka
- Oxhumana nabo, uma begcinwe ekhadini lakho le-SIM , ngeke bafinyeleleke ngekhadi le-SIM eliqashisayo
- Kuzodingeka unikeze inombolo entsha kubantu abazokuxhumana nawe
Qasha iselula
Nakuba kuyabiza ngaphezu kokuqasha i-SIM khadi, ukuqasha iselula ye-GSM esebenza lapho uya khona kukuvumela ukuba ufinyeleleke ngaso sonke isikhathi futhi wenze ucingo.
Izinzuzo :
- Ukuqashiswa kwefoni ngomakhalekhukhwini kuyatholakala emazweni angaphezu kuka-150 emhlabeni wonke ( abahlinzeki abaningi be-broadband abakhokhelwa ngamazwe emhlabeni wonke banikeza ukuqashiswa kwefoni yomhlaba jikelele)
- Ungagwema ukukhokhiswa ngokwezindleko kanye nemali yokuxhumeka eyengeziwe
Umthengi :
- Ngeke ube noxhumana nabo nolwazi olulondolozile efonini yakho
- Udinga ukunikeza inombolo entsha ukuze abantu baxhumane nawe
- Ukukhetha izinketho zefoni, ngakho-ke kungase kudingeke ufunde ukuhamba ngezinketho zefoni entsha
Sebenzisa i-VoIP Izingcingo ezivela kukhompyutha
Ukusebenzisa izinsizakalo zocingo ezise-intanethi njenge-Skype kungaba yindlela eshibhile yokwenza izingcingo zomhlaba wonke ; kungaba mahhala uma usebenzisa i- wi-fi hotspot yamahhala . Ukusebenzisa i-VoIP kusuka ku- cafe ye-intanethi ingaba engabizi kakhulu, kepha kokubili i-wi-fi hotspot nokusetshenziswa kwe-cafe net kuncike ekuziphatheni kwakho endaweni ethile.
Ungasebenzisa futhi i-VoIP kwikhompyutha yakho ephathekayo usebenzisa ukubhalwa kwe-mobile broadband okukhokhelwa ngaphambilini .
Izinzuzo :
- Kungabiza kakhulu (ngisho mahhala) uma usebenzisa i-VoIP nge-WiFi
Umthengi :
- Abanye abakwazi ukukufinyelela ngokushesha
- Kumele ube kwikhompyutha ukwenza izingcingo
- Kungaba kubiza ngokwezindinganiso zokuxhuma
