V b\u0159eznu jsem byl na Kub\u011b (Havana, Varadero a Trinidad) – cestopis\u016f na t\u00e9ma Kuba se d\u00e1 ur\u010dit\u011b naj\u00edt jinde nes\u010detn\u011b, ale p\u0159ipojen\u00ed k internetu si zaslou\u017e\u00ed zm\u00ednku na blog.<\/p>\n\n\n\n

Roaming \u010di m\u00edstn\u00ed SIMka? Zapome\u0148te<\/h2>\n\n\n\n

Roamovat mimo EU, je\u0161t\u011b nav\u00edc za oce\u00e1nem, by asi zkou\u0161el jen dobrodruh – pro zaj\u00edmavost, cena by byla 360 K\u010d za 1 MB.

Po m\u00edstn\u00ed SIMce jsem kv\u016fli 10 dn\u016fm netou\u017eil, nepot\u0159eboval jsem b\u00fdt online trvale, ale jen na p\u00e1r minut ka\u017ed\u00fd den kv\u016fli WhatsAppu a mailu. U\u017e takhle \u010dlov\u011bk vyst\u00e1l ve front\u00e1ch spoustu \u010dasu na mnohem d\u016fle\u017eit\u011bj\u0161\u00ed v\u011bci (t\u0159eba n\u011bco k j\u00eddlu), tak\u017ee nedok\u00e1\u017eu \u0159\u00edct, jestli by bylo nebo nebylo mo\u017en\u00e9 si ji po\u0159\u00eddit a kolik by SIMka st\u00e1la. Mimochodem jedin\u00e1 v\u011bc, na kterou se fronta nest\u00e1la, byl rum – toho m\u011bli dost i v \u017eelez\u00e1\u0159stv\u00ed.<\/p>\n\n\n\n

Tak\u017ee jasn\u00e9, ur\u010dit\u011b tam bude n\u011bjak\u00e1 free otev\u0159en\u00e1 wifina, kter\u00e1 se m\u011b ujme (n\u011bjak\u00e1 kav\u00e1rna nebo \u0161patn\u011b nastaven\u00e1 dom\u00e1cnost) – \u00fapln\u011b nejbezpe\u010dn\u011bj\u0161\u00ed n\u00e1pad to nen\u00ed, ale tak v\u0161ude je TLS atd., to p\u016fjde… – tak to ani n\u00e1hodou.<\/p>\n\n\n\n

Kdy\u017e u\u017e v\u016fbec n\u011bjakou wifi mobil uk\u00e1zal, tak zaheslovanou, moc ale ani takov\u00fdch nebylo.<\/p>\n\n\n\n

K internetu se d\u00e1 toti\u017e (alespo\u0148 pro turistu) p\u0159ipojit jen p\u0159es wifi od m\u00edstn\u00edho telekomu – ETECSA. Za internet se plat\u00ed 1 CUC (= 1 euro) za 1 hodinu. Ve skupince v\u00edce lid\u00ed je dobr\u00e9 m\u00edt Androida, kter\u00fd um\u00ed zhotspotovat i wifi p\u0159ipojen\u00ed – to pro v\u00e1s iPhone neud\u011bl\u00e1 a bude platit ka\u017ed\u00fd s\u00e1m.

Bu\u010f tak, \u017ee si nech\u00e1te v jedn\u00e9 z\u00e1lo\u017ece otev\u0159en\u00e9 okno ETECSY, kter\u00e9 m\u00e1 na sob\u011b tla\u010d\u00edtko Odhl\u00e1sit, a nebo t\u00edm, \u017ee vypnete wifinu – pak to ale nemus\u00ed b\u00fdt \u00fapln\u011b spolehliv\u00e9. Po zad\u00e1n\u00ed dan\u00e9ho \u010d\u00edsla kuponu se uk\u00e1\u017ee, kolik minut na n\u011bm zb\u00fdv\u00e1.<\/p>\n\n\n\n

U\u017e v\u016fbec placen\u00ed internetu za \u010das mi p\u0159ipomn\u011blo doby modemu a n\u00e1vyk\u016f jako pootev\u00edrat co nejv\u00edc \u010dl\u00e1nku do dal\u0161\u00edch tab\u016f, abych si je pak p\u0159e\u010detl offline.<\/p>\n\n\n\n

Co je nutn\u00e9 uznat – to p\u0159ipojen\u00ed nebylo \u0161patn\u00e9. \u0158ekl bych, \u017ee tak 1 megabit za sekundu minim\u00e1ln\u011b to \u0161lo, tak\u017ee v\u0161echny norm\u00e1ln\u00ed v\u011bci (WhatsApp i s obr\u00e1zky, Instagram…) \u0161ly tak n\u011bjak v re\u00e1ln\u00e9m \u010dase a to sta\u010d\u00ed.<\/p>\n\n\n\n

Co je ale neuv\u011b\u0159iteln\u00e9… plat\u00ed se st\u00edrac\u00edmi kupony, n\u011bco jako u n\u00e1s dob\u00edjec\u00ed kredit pro p\u0159edplacen\u00e9 karty. Ne, \u017ee by to nebyl funk\u010dn\u00ed zp\u016fsob, ale d\u00edky tomu zvl\u00e1dnou Kub\u00e1nci z p\u0159ipojen\u00ed k internetu ud\u011blat nedostatkov\u00e9 zbo\u017e\u00ed z toho \u00fapln\u011b nejnesmysln\u011bj\u0161\u00edho d\u016fvodu.<\/p>\n\n\n\n

Tud\u00ed\u017e, kdy\u017e jsme zjistili, kde v Havan\u011b ty z\u00e1zra\u010dn\u00e9 kupony na internet prod\u00e1vaj\u00ed (v hotelu pobl\u00ed\u017e Kapitolu), na recepci n\u00e1m potvrdili, \u017ee to jako ano, \u017ee kupony prod\u00e1vaj\u00ed, ale „dneska je\u0161t\u011b nep\u0159ijel autobus, kter\u00fd kupony voz\u00ed, zkuste to za 20 minut“ (napot\u0159et\u00ed vy\u0161lo). Podruh\u00e9, kdy\u017e jsme cht\u011bli p\u0159ikoupit trochu kupon\u016f v ofici\u00e1ln\u00edm ETECSA obchodu ve Varaderu, tak po 40minutov\u00e9 front\u011b jsem pan\u00ed za p\u0159ep\u00e1\u017ekou up\u0159\u00edmn\u011b pobavil t\u00edm, \u017ee jsem jich cht\u011bl 10, kdy\u017e je p\u0159eci limit 3 na osobu. Krom\u011b toho prod\u00e1n\u00ed t\u011bch 3 kupon\u016f trvalo asi 5 minut (u ka\u017ed\u00e9ho \u010dlov\u011bka ve front\u011b), snad evidovala jejich \u010d\u00edsla do n\u011bjak\u00e9 knihy nebo tak n\u011bco (samoz\u0159ejm\u011b „ID required“).<\/p>\n\n\n\n

V Trinidadu pak st\u00e1li na ulic\u00edch „p\u0159ekupn\u00edci“, prod\u00e1vali kup\u00f3ny se svoji p\u0159ir\u00e1\u017ekou (2 CUC za 1 hodinu nebo 5 CUC za 3h).<\/p>\n\n\n\n

„Walled gardens“ a free wifi<\/h2>\n\n\n\n

Tento \u010d\u00e1ste\u010dn\u011b neut\u011b\u0161en\u00fd stav internetu vede ke vzniku zaj\u00edmav\u00fdch „walled gardens“, kdy t\u0159eba divadlo m\u00e1 webovou prezentaci, ale jen ve sv\u00e9 vnit\u0159n\u00ed s\u00edti: plak\u00e1t v\u00e1m \u0159ekne, a\u0165 se p\u0159ipoj\u00edte na jejich wifi a po otev\u0159en\u00ed vnit\u0159n\u00ed IP adresy se pod\u00edv\u00e1te na jejich program – s internetem to moc spole\u010dn\u00e9ho nem\u00e1, ale asi to trochu funguje.<\/p>\n\n\n\n

I kdy\u017e jsem psal, a\u0165 na ve\u0159ejnou free wifi zapomenete, potkal jsem dv\u011b v\u00fdjimky – restauraci, kter\u00e1 inzerovala free wifi a m\u011bla na to dokonce i samolepku jako potvrzen\u00ed od TripAdvisoru.

Kdy\u017e kupon skon\u010dil, hodila i jejich wifi landing page „zadejte kupon“.
