Should you update your GPP unlocked iPhone?




GPP is a SIM spoofing tool that is inserted into a carrier locked phone along with your local SIM in order to bypass the carrier restrictions and can be used on local networks. However, this SIM tool usually has limitations such as no LTE support and firmware compatibility, meaning if iOS updates to the latest version, the tool might not work. GPP unlocked iPhones are way cheaper than factory unlocked iPhones as a majority of these are region or carrier locked or even refurbished, possibly stolen surplus iPhones coming from China, Korea, and Japan.

Apple routinely releases a new version of its operating system, better known as iOS, whenever it introduces new phones. iOS 11, which is the most recent major update, was released on Sept. 19, followed by minor updates on Sept. 26 (11.0.1), Oct. 3 (11.0.2), Oct. 11 (11.0.3) and Oct. 31 (11.1). As of this writing, 11.2.5 is in beta testing and should be released in the near future as the common complaint of reduced battery performance seems to have cropped up, as it has with many past versions. So, should you update your GPP unlocked iPhone? The answer is a mixed bag. Yes, you could, but there are obvious caveats.

Updating your GPP unlocked iPhone into its latest version comes with a wide variety of new features and also, problems. It is a hit or miss whether the GPP chip you’re using will still work as the update may contain a fix that will prevent you to continue using your local SIM card. Apple is also updating and restricting ICCID which is a unique number assigned to a SIM card on your iPhone, prompting your device to be activated again. Good thing is, that the latest GPP chip available on the market nowadays offers a feature where you can manually edit the ICCID so that it will still work on future iOS updates. Some users are also confirming that you will only encounter some problems if you remove or re-insert a SIM card and resetting your device to its factory setting after the latest update. My brother is using a GPP unlocked iPhone, updated to iOS 11.2.5 Developer Beta 2, with the latest LTE GPP chip installed. He has yet to encounter any major problems during his first two months, as his iPhone 8 Plus’ hardware still works well with the latest updates.

That said, you should also consider what device you’re using. iOS 11 takes up more space and takes more computing power than its predecessor meaning it could slow down older devices. Obviously, your mileage will vary depending on lots of other factors; however, if you’re still using a much older device, it may be best to hold off on updating to the latest iOS version until you get some new hardware.

Before you install any iOS update, you can always click on the link in the description to see what new features are being added and what bugs or security issues are being addressed. If the new features aren’t that compelling like new emojis or you’re not experiencing any issues listed, holding off on the update makes sense. Unless, of course, Apple expressly denotes that it’s a serious security patch and you have the extra money to buy the latest GPP chip available on the market or seek for a service that will unlock your iPhone permanently.

    OT, since when a smart locked iphone 6s+ can use a sun sim? im using a sun lte sim and its working, my old sun sim cannot. im on a 10.3.3 ios version. i dont want to update yet to 11.

    • Mel says:

      Sun’s new LTE SIM cards now use Smart’s own GSM network code (515-03) basically making it a Smart SIM card with Sun branding (same with Talk ‘n Text SIM cards) making it work with Smart-locked handsets.

      Older non-LTE SIM cards of Sun use the old (pre-Smart merger) 515-05 GSM network code and won’t work on Smart-locked handsets.

    In some countries, locking phones to a network is prohibited. Kelan kaya mangyayari yan sa ating bansa?

  3. Kamen Rider Build says:

    Wait till the contract period expires then ask your network carrier to unlock it for you :) That’s the easiest way :)

  19. Lloyd Kenn says:

    Iphone 6s ang phone ko, pero GPP unlock. Ang problema, nakalimutan ko at di ako na aware agad na nag shutdown pala ang GPP chips. So, nung tinanggal ko para mag change sana ako ng sim, di ako makapalit. So I decided na ibalik nalang ang old sim, pero pagbalik ko di na pwede at need activation na. ?Kaya, Sabi nang nabilhan ko ng phone, hintay lang dw ako sa bagong ICCID. Ang tanong ko lang, hanggang kelan kaya ako maghihintay sa ICCID ?? mag wa-one na kasi mula nung tinanggal ko ang sim.

    • Hazel says:

  52. Joe says:

    hello guys, It’s it okay to your 5s battery to 2600 MAH?

    i want to change my battery. my phone got easily drained, the battery is not good anymore.

    I have read in some online shop regarding with the battery mah is higher than the regular battery of 5s which is 1560 mah. Any advice those who have upgraded their battery? 1560 to 2600mah is safe for iphone 5s? I have doubt though i want to. but I am worried if it may explode my device. So I want to have some opinion from those who did updrade their 5s battery.

    • PeterthePanda says:

      Fake battery yun. Walang totoong battery for iPhone 5s na 2600 mAh. Yung naka-gold na battery na sinasabi na 2600mAh eh fake. Re-packaged na iPhone 5s battery lang yun na 1570mAh, malamang pa nga lumang battery na yun na mabilis ma-drain.

  53. Jay-ar says:

    Hi po ask ko lang po gpp user ako pagtapos nag update ko using itunes hindi ko na ma gamit yung sim nagkakasignal sya tapos nag no service tapos bumabalik sa “Your iphone successfully updated” need ng few more step tapos yun pag nanconnect sa wifi bumalik na nman sa menu tapos mayat maya bumabalik na nman “iphone successfully updated paulit-ulit lang po?

    Ang sabi skin ng pinagbilhan ko ng gpp lte, 1 gpp lte per sim only, pag ibang sim na ang gagamitin, another gpp lte uli. Kumbaga 1:1 lang po..

    What if I didn’t use na my gpp bc it was broke in a year. Is it okay pa din na iupdate? May effects ba na mangyayari or wala? Ty

  63. Julie rose says:

    Updated my 5s accidentally to 11.4 ios so far it runs smoothly… i didnt change gpp lte chip, i still use my globe sim. Thanks.

  64. Princess says:

    Hello, I’m using iphone 5s naka gpp din po ako bale mag one year pa lang po. Pero sabi nila masisira daw po yung gpp pag nag update to ios12? Totoo po ba?

  65. Hazel says:

    Hi good day po! I updated my iphone 6 plus just this sept 12. Before I tried to check for an update, I tried to insert my globe sim, and to my surprise, gumana ung globe sim with gpp chip.. Then just now I tried to insert my smart sim together with the gpp I bought back to the iphone6plus, it showed no sim. Mukhang nasira ko ata ung gpp ko worth 500php ?. Then naisip ko ilagay ung smart without the gpp chip, to my surprise, gumana ung smart sim ko! Ang saya ko po, promise! I dont know kung dhil sa update na iOS12 un or what. Now I’m wondering kung dahil ba sa security pin ko noon na naka ON kung bakit ayaw gumana ng smart ko before, at ngaun ay dahil naka OFF ung security pin at fingerprint lock nung nilagay ko ung smart sim ko ay saka gumana. Or maybe wala tlga kinalaman sa security pin at fingerprint lock? Pls enlighten me. Pero kasi dati wala tlga syang tinatanggap na khit anong sim eh, kaya nga nkipagpalit skin ng phone ang dad ko dhil di nya malagyan ng sim ung ip6plus.

    • Joebert Pangga says:

      hello ma’am hazel,
      gpp po ba talaga phone na gamit nyo po? kasi very surprising naman po kung gumana yung sim mo na walang na insert na GPP chip.

      as far as I know po. 1 GPP is to 1 sim only. pero parang di na tatanggap ng ibang sim ang gpp kapag nag update ng ios na-as my experienced po kasi, nung bago pa po yung phone ko 2 beses ako nagpalit nang si. una TM gamit ko, pero pinalitan ko po ng tnt. pero nong na update ko na po ios ko ng maraming beses sinubukan ko ulit magpalit ng sim na sun. pero ayaw na po tumanggap ng sun sim, or tn sim. yung tnt ko lang ang gumagana sa gpp ko after na ma update ko na ng maraming beses.

    • Hazel says:

      Hello po sir Joebert Pangga, actually po sir galing sa ate ko ung phone na gamit ko na nasa USA. Old phone nya po for plan. AT&T po ata ung network nya dun. Nung una po kasi ayaw gumana khot anong sim nung bagong bigay skin ung phone, globe ayaw, smart ayaw din. Kaya naisipan ko bumili ng gpp chip then smart ang nilagay ko kasama ng gpp chip then gumana naman po. Yes po sir alam ko po na 1:1 lang po, 1gpp chip : 1simcard. Then nung bumiki ako ng globe, out of nowhere naisipan ko ilagay ung globe sim without the gpp chip, then to my surprise gumana ung globe. Then weeks later naisipan ko naman ilagay ung smart sim ko uli without the gpp chip, then ayun nagulat din ako kc gumana din. Hindi ko po ginamit sa glove ung gpp chip. Sa smart ko lang po ginamit un before nung ayaw gumana. Kaya po kung mababasa nyo po sa comment ko sa taas, nabanggit ko doon na hindi ko sure kung dhil ba sa update or kung dahil ba sa nka off ung security lock code ko nung nilagay ko ung smart ko. Before kc bago ako bumili ng gpp, ayaw tlga gumana ng smart ko, naka sim lock daw or network lock, etc. Then hanggat hindi ko tinatanggal ung smart sim sa phone, hindi mo maoopen or mauunlock ung phone dba, that time I think naka ON ung security lock code at fingerprint lock ko..

    • Hazel says:

      @Joebert Pangga sir sakin po khit after ko mag update to iOS12, gumana prin po gpp chip ko with my smart sim. Kaso nitong isang araw lang nagtaka ako kung bkit biglang ayaw na gumana ng gpp chip ko nung nilagay ko smart ko, no sim nkalagay, then dun ko naisip ilagay ung smart without the gpp chip. Then ayun po, gumana ung smart without gpp chip. I think it has something to do with the security lock code & fingerprint lock? Na kapag nka on un at naglagay ka ng sim ay sim locked ung phone, then japag naka off nman ay working naman ung sim..? Not sure sir, kaya po nagshare din ako ng experience ko dito kc baka meron nkakaalam…

  66. Hazel says:

    Sorry, my mistake po, without gpp po nung nilagay ko ung globe ko.. sorry for the confusion. ?

  67. Fred says:

    Anyone updated their GPP unlock iPhone 6 from ios 11.4.1 to ios 12.1?

    Thanks po

  69. Rolando says:

    Kung hindi pa po updated yong gpp chips po tapos need iupdated yong mga apps magshutdown po ba kapag nagupdated? or magrestart?
    Thanks po

  70. Aileen Roman says:

    Ah gpp pala yun. Sus, napaka hassle naman pala nyan, hindi pede reset, hindi pede updates, tapos lagay ka bago code etc. Yung iPhone ko no need gumamit ng ganyan. Sa susunod kasi bago kayo bumili ng iPhone make sure hindi yan naka lock sa carrier, make sure yung nagbenta sa inyo nyan totally finormat at nirestore sa factory reset without any iCloud account active at ipinakita na gumagana sa harap nyo at syempre make sure hindi yan pulot or nakaw. Yung iba kasi nating kababayan, masabi lang na naka iPhone kahit sumakit ulo sa ganitong klaseng hassle magtitiis… ay sos mga hinayupak kayo.
