Hi, Communnity hopefully you're the way to HK but l want to know how to access mobile in Tanzania we have VODACOM, TIGO, AIRTEL, TTCL, sASATEL and ZANTEL so l want to know among of all those is any one operating in HK?.. Simplly l can use with my sim card?.. Without any changes?..
if you have a regular GSM SIM card and contract with a GSM provider you have the ability to "roam" between your home network and foreign networks abroad with which your network provider has roamining arrangements. Vodacom for instance is internationally Vodafone and that one has many roaming partners and also many branches in other countries.
So yes, you should be able to bring your mobile phone with your SIM card and it will just work in Hong Kong. Sometimes frequencies might differ, that is why mobile phones are sold as "single band", "dual band", "triple band" or even "quad band". In Tansania GSM 450, GSM 900 and GSM 1800 are in use, in Hong Kong GSM 900 and GSM 1800 are in use. So that should work for you as well.
Be aware that using your tansanian SIM card abroad, while roaming, adds a lot of additional costs compared to the fees you pay at home. You pay the regular fees of your provide plus and additional fee for the roaming provider, both for incoming and outgoing calls.
Alternatively you can buy a cheap local prepaid SIM card to be used while you are in Hong Kong. You can get it at any 7-11 store for 78 HKD with one week 3G data. (1 USD = 8 HKD, 1 EUR = 10 HKD). So if you have a phone with no SIM lock you could use that offer instead and just exchange the SIM cards while you are in Hong Kong.
