I believe that's possible. Just visit any Globe centers and ask to have your SIM replaced with an LTE SIM. LTE will only work if you have an LTE SIM. Globe can just transfer same account information.
You can have it replace at the Globe Store. Free of charge. Make sure to back up the contacts you have in your old sim and bring a valid copy of ID at the Globe sotre, if in case your not available authorization letter and valid copy of your Id will do. Nothing will change in your account, you will retain your old postpaid no.
You may request for sim activation and LTE provisioning at the globe store if you are going to request NANO-LTE sim.
Reminder: LTE provisioning and Nano sim activation should be processed together. And not all places here in Metro Manila (Philippines) is covered by LTE services.... To know more of the location just log on to www.globe.com.ph then search for 4G SITES.
Thank you for your replies. Basically the problem is, the interposer sim doesnt read my 128k sim's 3g/4g network. I'm only getting EDGE signal from it. When we tried using regular 64k sim cut into nano size, it receives the 3G signal without any problem. The only solution i can think of right now is to request for a 64k globe postpaid sim. I tried calling their hotline and the rep told me he doesn't have the acces to that information. (Lame excuse) Then i went to globe store but the csr told me they only provide 128k postpaid sims. *sigh* Now i'm unable to take advantage of my unlisurf.
just visit any globe store so they can see your handset and then after they inspect the handset they will be the one to know what kind of sim card is needed in your handset just bring 1 valid id and the old sim to be replaced you may also relay the problem you are encountering so they can check on it... dont wori i believe they have person there that know a lot regarding the handset they can help you with your concern...
Just an update guys. I went to globe store sm fairview and they weren't able to replace my 128k sim. As i mentioned, the interposer sims that are available today doesn't recognize 128k sim cards for you to use 3G/LTE signals. The CSR told me that they only provide 128k sim cards for postpaid and 32/64 for prepaid subscribers. I also asked if they can have a 32/64k sim provisioned so i can use the bundle/plan that i am subscribed to but they told me it wasn't possible. Right now, i can only use EDGE on both of my unlidata plans which is too slow.
