hi! i wanna buy iphone 6 at this IG seller.she said its a new original MY set.does Malaysia set have lock carrier phone? means like US set phone.and what if i buy from digi,is it same? lock phone and not support 4G malaysia.because last time i bought my iphone 5 at this phone shop and claimed its 'NEW' and 'SINGAPORE SET'.but after i check,its a US SET.because is stated there 'LL'(US) not 'ZA'(SINGAPORE) and i never get 4G sign at my network.ive changed my sim card few times and enable 4G at settings but it doesnt work.then i went to this phone shop at lowyat and the guy said 'ini phone US tak support 4G malaysia punya'.that means my phone is a carrier locked phone?

1st question.if i buy iphone 6 my set,then wil it be any problem with the band?
2nd question.how to solve the band problem? is it related to GSM or CDMA problem?

ohh i see.how to know whether 'the' iphone 5's band compatible to all network in malaysia? how to check before buy it?
