Nyob rau nees nkaum xyoo dhau los, SIM phaib tau txo ob zaug loj, thiab tam sim no thaum yuav ib lub xov tooj tshiab koj yuav tsum tau xyuam xim rau hom SIM daim npav nws siv. Hauv tsab xov xwm no, peb yuav tham txog yam thiab qhov ntau thiab tsawg ntawm SIM phaib Apple siv hauv nws lub xov tooj smartphones.
History of Appearance
Thawj lub xov tooj ntawm tes tsis muaj SIM phaib thiab siv tus lej mus tas li ua tus cim hauv lub xov tooj ntawm tes. Txoj hauv kev no tsis haum rau thawj tus tswv ntawm tes lossis cov neeg siv lawv tus kheej. Muaj ib lub tswv yim hais txog qhov yuav tsum tau tsim lwm qhov system los txheeb xyuas cov neeg siv khoom, uas yuav yooj yim rau txhua tus, uas ua rau kev txhim kho ntawm SIM phaib. Cov keeb kwm ntawm thawj cov cuab yeej cuab tam hauv cov xov tooj ntawm tes niaj hnub yog tus lej IMEI tshwj xeeb. Nws raug xa mus rau txhua lub xov tooj thaum lub sijhawm tsim khoom thiab tsis hloov pauv thaum nws lub neej.
Technologically, SIM card yog ib lub computer mini. Nws muaj nws tus kheej processor, cov ntaub ntawv kaw lus thiab nco, mus tas li thiab ua haujlwm. Rau lub hom phiaj kev ruaj ntseg, daim npav muaj ib tug built-in neeg siv cov ntaub ntawv encryption system. Lub peev xwm ntawm lub khoos phis tawj me me no yog siv los ntawm cov neeg siv xov tooj ntawm tes los tsim ntau hom kev kosmenu.
Hom thiab ntau thiab tsawg
Nyob rau hauv tag nrho, peb tus qauv qhov ntau thiab tsawg ntawm cov neeg siv khoom hloov pauv cov cim npe (SIMs) tau siv:
- Mini SIM (25 x 15 x 0.76).
- Micro SIM (15 x 12 x 0.76).
- Nano SIM (2 x 9 x 0.65).
Qhov ntev ntawm cov npe no sib haum rau qhov ntev, dav, tuab thiab nyob rau hauv millimeters.
Hom daim npav tseem ceeb siv txij li xyoo 1996 yog mini-sim. Micro-sims tau tsim tawm txij li xyoo 2004 thiab kuj tau nthuav dav heev. Hom tshiab tshaj plaws tsim yog nano-sim. Nws tshwm sim hauv xyoo 2012 thiab tau siv ntau yam niaj hnub smartphones.
Qhov loj ntawm daim npav cuam tshuam nrog qhov ntev ntawm cov khoom siv txawb lawv tus kheej. Txo qhov tuab ntawm cov xov tooj thiab qhov chaw sab hauv hauv rooj plaub ua rau cov tuam txhab hloov pauv hom SIM daim npav. Micro-sim, uas txhais tau tias "me" lossis "txo", yog thawj zaug siv los ntawm Apple. Tus txheej txheem tshiab loj tau siv nyob rau hauv iPhone 4. Thaum tuav cov kev txwv ntawm lub ntsiab nti, daim npav poob cov yas substrate nyob ib puag ncig nws. Rau qee lub sijhawm, ua tsaug rau cov tuab tuab thiab kev ua haujlwm yooj yim, mini-sim tau yooj yim "txiav" rau qhov loj me.
Cov neeg siv xov tooj ntawm tes thaum kawg tau yoog rau cov txheej txheem ntawm cov ntawv muaj, thiab tam sim no, thaum yuav ib daim npav SIM hauv txhua lub khw, koj tau txais nws hauv hom "matryoshka". Tag nrho peb qhov ntau thiab tsawg tau nthuav tawm ntawm ib lub phaj thiab tsuas yog sib cais los ntawm qhov qhib, ua tsaug uas koj tuaj yeem xaiv qhov yog. Ntawmqhov yuav tsum tau siv lub qub smartphone qauv nrog SIM daim npav tshiab, lub plhaub sab nraud ntawm no "matryoshka" ua raws li kev hloov pauv, txij li cov nti tswj tau tsuas yog "nano" loj.
iPhone and SIM cards
Tau ntau xyoo ua tus trendsetter thiab trendsetter hauv kev lag luam txawb, "apple company" yeej ib txwm yog thawj zaug siv hom SIM phaib tshiab. Raws li peb twb paub lawm, plaub tus qauv ntawm iPhone coj mus rau qhov zoo li "micro" loj. Ob peb xyoos tom qab, Apple rov hloov hom SIM daim npav. Hauv iPhone 5S, zoo li hauv txhua lub xov tooj ntawm lub tuam txhab no, pib ntawm "tsib" thiab xaus nrog "xya", tsuas yog siv "nano" loj.
Yog li, txhua tus qauv iPhone niaj hnub siv ib daim npav SIM tus qauv. Cov uas tsis siv lawm tab sis tseem siv iPhone 4 thiab 4S yuav xav tau daim ntawv thov "micro", thiab rau cov xwm txheej qub, uas suav nrog 3 thiab 3G - "mini". Qhov xwm txheej zoo ib yam nrog cov ntsiav tshuaj ntawm lub tuam txhab no. Txhua cov ntaub ntawv hais txog SIM phaib siv tau tuaj yeem pom ntawm nplooj ntawv Apple technical support.
In xaus
Tom qab kawm peb cov khoom, koj tau txais kev paub tsawg kawg nkaus uas tsim nyog txog SIM phaib, lawv hom, qhov ntau thiab tsawg thiab siv hauv Apple li.
