Vodafone has already launched 4G services in 17 states. Here is process to swap and activate your 4g sim.
- Get a 4G sim from any vodafone store by giving the requested matching documents(I don’t think they ask for it any more) and sim fees(if any), I got sim free.
- Don’t take out your old sim from phone yet. Send sms your existing Vodafone sim to 55199 write “SIMEX < 19-20 digit 4G SIM card number printed on New sim card itself>”
- You will receive a reply from 55199 with half SIM number entered asking you to reply with remaining six digit sim no.
- You have 2 hours after receiving that sms to send remaining 6 digits of sim no to 55199.
- You’ll receive success sms in next 5-10 minutes if not then start from step 2 again.
- Now wait for network to disappear and change to new sim only after that. Enjoy 4G!
I think vodafone process can be little cumbersome for some people as you need to send sim no twice which can confuse many people. Airtel got a better process where you need to send sim no just once and confirm with a 1 that’s it.
Update: I just visited voda store here in Delhi, the rep just asked me my mobile no , entered it in his system and gave me a prepaid 4G sim and asked me to do step 3, 4 and 5 in front of him. That’s it.

i want 4g sim vodafone by ussd code please help me
Well explained. It worked. upgraded to 4G within 30 minutes.!!! Thanks for sharing!!
Glad it worked. Enjoy!
4g not activated on my new Vodafone SIM why
maybe some backend problem or voda 4G network problem. Call 198 to complain. Voda got least 4G coverage out of big 4.
Contact me upgrade for Vodafone 4g
Visit vodafone store to get 4G sim. No point to contact anyone.
Dear i got the 4G sim and update also but the charges is very high. Now can i convert my 4g sim in 3g sim back if any procedure for that
you can use it for 3G sim also. Just put back your phone to 3G only mode. Though I doubt that 3G tariff are cheaper. 3G n 4G tariff are same.
I just got a 4G SIM as replacement but when I text th 20 digit SIM number to 55199, the only response I get is: “Kindly send the last 6 digots of the SIM number to continue the activation process.”
I never received any response SMS with half SIM number entered.
Maybe they changed the process , better to reply as sms says.
SMS act 4G not activated
Check if sim no typed is correct. Most common problem.
